Set type to "multivariate".

multivariate SummarizeMultivariate

​

Fields of SummarizeMultivariate
inputs array of MultivariateInput

List of input series to temporally align at the raw point level, then bucket the aligned tuples together. The series with the largest tag group acts as the “driver” that determines which raw timestamps are included in the alignment. All subsequent series are aligned to the driver’s raw timestamps using the interpolation configuration. After alignment, the resulting (x, y, z, …) tuples are bucketed into time windows and aggregated.

outputFormat OutputFormat

The output format of the response. Defaults to LEGACY (JSON).

bucketCount integer

The number of buckets to return in the response. Maximum is 10,000. Defaults to 1,000 if not specified.

interpolationConfiguration InterpolationConfiguration

Controls how the N input series are aligned at the raw point level when producing multivariate buckets. When present, the server may fill forward a series value from the most recent prior raw point (bounded by the interpolation radius). This alignment happens BEFORE bucketing, ensuring that aggregated values in each bucket are computed from temporally aligned raw tuples. When absent, the default interpolation configuration is used.

start Timestamp required

The start of the time range (inclusive).

Fields of Timestamp
seconds integer (int64) required

​

​

datasetReferences map of DatasetReferenceName to Dataset

Named datasets looked up by DatasetReference nodes in the compute tree.

Set type to "asset".

asset Asset

Single asset. Expands to one grouping per data scope on the asset. Groupings are tagged by assetRid and dataScope so callers can safely compose multiple assets with combine.

Set type to "run".

run Run

Single run. Expands to one grouping per data source attached to the run: asset-typed sources contribute one grouping per data scope on the asset; dataset-typed sources contribute one grouping per dataset. Groupings are tagged by runRid and dataScope; asset-typed groupings additionally carry assetRid so callers can safely compose multiple runs with combine.

Set type to "driverSeries".

driverSeries DriverSeries

​

Set type to "union".

union Union

​

applyDataScopeOffsets boolean

When true, dataset resolution applies each data scope’s persisted offset as a time shift, and the client must not pre-apply those offsets itself. When absent or false, scope offsets are left to the client, preserving behavior for legacy clients that inject equivalent timeShift nodes into the compute request. Read from the context in scope at resolution time.

resolveAssetsThroughDatasets boolean

When true, Dataset.asset, the asset-typed sources of Dataset.run, and asset or run search expand through each asset’s mirrored derived dataset instead of its data scopes. Branches then carry the dataset’s declared channel-search split tag keys in place of the reserved DATA_SCOPE tag, so callers must filter and group on those keys; the definition’s own time shifts apply regardless of applyDataScopeOffsets; and an asset with no mirrored dataset resolves to no data. When absent or false, assets expand from their data scopes as before.

sourceRid string (RID)

Optional RID identifying the resource that initiated this query (e.g. workbook/notebook RID, checklist RID, dataset RID). Used for observability only — trusted as-is, no permission checks are performed on this value.

requestId string (UUID)

multivariate SummarizeMultivariate

​

Fields of SummarizeMultivariate
inputs array of MultivariateInput

List of input series to temporally align at the raw point level, then bucket the aligned tuples together. The series with the largest tag group acts as the “driver” that determines which raw timestamps are included in the alignment. All subsequent series are aligned to the driver’s raw timestamps using the interpolation configuration. After alignment, the resulting (x, y, z, …) tuples are bucketed into time windows and aggregated.

outputFormat OutputFormat

The output format of the response. Defaults to LEGACY (JSON).

bucketCount integer

The number of buckets to return in the response. Maximum is 10,000. Defaults to 1,000 if not specified.

interpolationConfiguration InterpolationConfiguration

Controls how the N input series are aligned at the raw point level when producing multivariate buckets. When present, the server may fill forward a series value from the most recent prior raw point (bounded by the interpolation radius). This alignment happens BEFORE bucketing, ensuring that aggregated values in each bucket are computed from temporally aligned raw tuples. When absent, the default interpolation configuration is used.

​

datasetReferences map of DatasetReferenceName to Dataset

Named datasets looked up by DatasetReference nodes in the compute tree.

Set type to "asset".

asset Asset

Single asset. Expands to one grouping per data scope on the asset. Groupings are tagged by assetRid and dataScope so callers can safely compose multiple assets with combine.

Set type to "run".

run Run

Single run. Expands to one grouping per data source attached to the run: asset-typed sources contribute one grouping per data scope on the asset; dataset-typed sources contribute one grouping per dataset. Groupings are tagged by runRid and dataScope; asset-typed groupings additionally carry assetRid so callers can safely compose multiple runs with combine.

defaultFillStrategy FillStrategy

Default fill strategy applied at every multi-input alignment boundary where no per-node interpolationConfiguration is specified. When absent, falls back to the server-configured default (forward fill with a 1 second fill limit).

Set type to "forwardFill".

forwardFill ForwardFill

​

defaultAlignmentStrategy Alignment

Default alignment strategy applied at every multi-input alignment boundary where no per-node alignment strategy is specified. When absent, falls back to the server default (driver-series alignment).

Set type to "driverSeries".

driverSeries DriverSeries

​

Set type to "union".

union Union

​

applyDataScopeOffsets boolean

When true, dataset resolution applies each data scope’s persisted offset as a time shift, and the client must not pre-apply those offsets itself. When absent or false, scope offsets are left to the client, preserving behavior for legacy clients that inject equivalent timeShift nodes into the compute request. Read from the context in scope at resolution time.

resolveAssetsThroughDatasets boolean

When true, Dataset.asset, the asset-typed sources of Dataset.run, and asset or run search expand through each asset’s mirrored derived dataset instead of its data scopes. Branches then carry the dataset’s declared channel-search split tag keys in place of the reserved DATA_SCOPE tag, so callers must filter and group on those keys; the definition’s own time shifts apply regardless of applyDataScopeOffsets; and an asset with no mirrored dataset resolves to no data. When absent or false, assets expand from their data scopes as before.

sourceRid string (RID)

Optional RID identifying the resource that initiated this query (e.g. workbook/notebook RID, checklist RID, dataset RID). Used for observability only — trusted as-is, no permission checks are performed on this value.

parameterizedContext ParameterizedContext required

Specifies how certain variables should be parameterized. If a variable name appears in both the context and the parameterized context, it will be treated as parameterized.

Fields of ParameterizedContext
parameterInputs array of ParameterInput

Each parameter input provides a satisfying set of values for the parameterized compute node.

Fields of ParameterInput

Compute units#

POST /compute/v2/compute/units

Returns the resulting unit for the output of a compute graph. If the resulting unit is equivalent to exactly one existing unit in the system, it will be returned (for example, a series in Coulombs divided by a series in Volts will return an output of Farads). If the output does not have units (for example, a range output,) the unit result will return noUnitAvailable, and if the computation was not successful, corresponding errors are returned.

multivariate SummarizeMultivariate

​

Fields of SummarizeMultivariate
inputs array of MultivariateInput

List of input series to temporally align at the raw point level, then bucket the aligned tuples together. The series with the largest tag group acts as the “driver” that determines which raw timestamps are included in the alignment. All subsequent series are aligned to the driver’s raw timestamps using the interpolation configuration. After alignment, the resulting (x, y, z, …) tuples are bucketed into time windows and aggregated.

outputFormat OutputFormat

The output format of the response. Defaults to LEGACY (JSON).

bucketCount integer

The number of buckets to return in the response. Maximum is 10,000. Defaults to 1,000 if not specified.

interpolationConfiguration InterpolationConfiguration

Controls how the N input series are aligned at the raw point level when producing multivariate buckets. When present, the server may fill forward a series value from the most recent prior raw point (bounded by the interpolation radius). This alignment happens BEFORE bucketing, ensuring that aggregated values in each bucket are computed from temporally aligned raw tuples. When absent, the default interpolation configuration is used.

​

datasetReferences map of DatasetReferenceName to Dataset

Named datasets looked up by DatasetReference nodes in the compute tree.

Set type to "asset".

asset Asset

Single asset. Expands to one grouping per data scope on the asset. Groupings are tagged by assetRid and dataScope so callers can safely compose multiple assets with combine.

Set type to "run".

run Run

Single run. Expands to one grouping per data source attached to the run: asset-typed sources contribute one grouping per data scope on the asset; dataset-typed sources contribute one grouping per dataset. Groupings are tagged by runRid and dataScope; asset-typed groupings additionally carry assetRid so callers can safely compose multiple runs with combine.

defaultFillStrategy FillStrategy

Default fill strategy applied at every multi-input alignment boundary where no per-node interpolationConfiguration is specified. When absent, falls back to the server-configured default (forward fill with a 1 second fill limit).

Set type to "forwardFill".

forwardFill ForwardFill

​

defaultAlignmentStrategy Alignment

Default alignment strategy applied at every multi-input alignment boundary where no per-node alignment strategy is specified. When absent, falls back to the server default (driver-series alignment).

Set type to "driverSeries".

driverSeries DriverSeries

​

Set type to "union".

union Union

​

applyDataScopeOffsets boolean

When true, dataset resolution applies each data scope’s persisted offset as a time shift, and the client must not pre-apply those offsets itself. When absent or false, scope offsets are left to the client, preserving behavior for legacy clients that inject equivalent timeShift nodes into the compute request. Read from the context in scope at resolution time.

resolveAssetsThroughDatasets boolean

When true, Dataset.asset, the asset-typed sources of Dataset.run, and asset or run search expand through each asset’s mirrored derived dataset instead of its data scopes. Branches then carry the dataset’s declared channel-search split tag keys in place of the reserved DATA_SCOPE tag, so callers must filter and group on those keys; the definition’s own time shifts apply regardless of applyDataScopeOffsets; and an asset with no mirrored dataset resolves to no data. When absent or false, assets expand from their data scopes as before.

​

end Timestamp required

Fields of Context
variables map of VariableName to VariableValue

​

functionVariables map of FunctionReference to FunctionVariables deprecated

Deprecated: This field is deprecated and will be removed in a future version.

datasetReferences map of DatasetReferenceName to Dataset

Named datasets looked up by DatasetReference nodes in the compute tree.

defaultFillStrategy FillStrategy

Default fill strategy applied at every multi-input alignment boundary where no per-node interpolationConfiguration is specified. When absent, falls back to the server-configured default (forward fill with a 1 second fill limit).

defaultAlignmentStrategy Alignment

Default alignment strategy applied at every multi-input alignment boundary where no per-node alignment strategy is specified. When absent, falls back to the server default (driver-series alignment).

applyDataScopeOffsets boolean

When true, dataset resolution applies each data scope’s persisted offset as a time shift, and the client must not pre-apply those offsets itself. When absent or false, scope offsets are left to the client, preserving behavior for legacy clients that inject equivalent timeShift nodes into the compute request. Read from the context in scope at resolution time.

resolveAssetsThroughDatasets boolean

When true, Dataset.asset, the asset-typed sources of Dataset.run, and asset or run search expand through each asset’s mirrored derived dataset instead of its data scopes. Branches then carry the dataset’s declared channel-search split tag keys in place of the reserved DATA_SCOPE tag, so callers must filter and group on those keys; the definition’s own time shifts apply regardless of applyDataScopeOffsets; and an asset with no mirrored dataset resolves to no data. When absent or false, assets expand from their data scopes as before.

sourceRid string (RID)

Optional RID identifying the resource that initiated this query (e.g. workbook/notebook RID, checklist RID, dataset RID). Used for observability only — trusted as-is, no permission checks are performed on this value.

requestId string (UUID)

Optional UUID to provide as a handle to selectively cancel the execution of this compute request.

Batch compute units#

POST /compute/v2/compute/batch-units

Same as computeUnits, however this endpoint functions on a batch of requests for wire efficiency purposes. An extra note is that this method will serialize underlying classic REST errors into the BatchComputeUnitResult type, meaning callers are required to check for errors explicitly (rather than relying on exceptions being thrown).

Body

requests array of ComputeUnitsRequest

​

Fields of ComputeUnitsRequest
node ComputableNode required

​

Set type to "ranges".

ranges SummarizeRanges

​

Set type to "series".

series SummarizeSeries

​

context Context required

​

Fields of Context
variables map of VariableName to VariableValue

​

functionVariables map of FunctionReference to FunctionVariables deprecated

Deprecated: This field is deprecated and will be removed in a future version.

datasetReferences map of DatasetReferenceName to Dataset

Named datasets looked up by DatasetReference nodes in the compute tree.

defaultFillStrategy FillStrategy

Default fill strategy applied at every multi-input alignment boundary where no per-node interpolationConfiguration is specified. When absent, falls back to the server-configured default (forward fill with a 1 second fill limit).

defaultAlignmentStrategy Alignment

Default alignment strategy applied at every multi-input alignment boundary where no per-node alignment strategy is specified. When absent, falls back to the server default (driver-series alignment).

applyDataScopeOffsets boolean

When true, dataset resolution applies each data scope’s persisted offset as a time shift, and the client must not pre-apply those offsets itself. When absent or false, scope offsets are left to the client, preserving behavior for legacy clients that inject equivalent timeShift nodes into the compute request. Read from the context in scope at resolution time.

resolveAssetsThroughDatasets boolean

When true, Dataset.asset, the asset-typed sources of Dataset.run, and asset or run search expand through each asset’s mirrored derived dataset instead of its data scopes. Branches then carry the dataset’s declared channel-search split tag keys in place of the reserved DATA_SCOPE tag, so callers must filter and group on those keys; the definition’s own time shifts apply regardless of applyDataScopeOffsets; and an asset with no mirrored dataset resolves to no data. When absent or false, assets expand from their data scopes as before.

Response

results array of ComputeUnitResult

​

Set type to "single".

Compute with units#

POST /compute/v2/computeWithUnits

Computes the output of the compute graph specified by a ComputeNodeRequest, as well as providing the resulting unit for the output of a compute graph. If the resulting unit is equivalent to exactly one existing unit in the system, it will be returned (for example, a series in Coulombs divided by a series in Volts will return an output of Farads). If the output does not have units (for example, a range output,) the unit result will return noUnitAvailable, and if the computation was not successful, corresponding errors are returned.

multivariate SummarizeMultivariate

​

Fields of SummarizeMultivariate
inputs array of MultivariateInput

List of input series to temporally align at the raw point level, then bucket the aligned tuples together. The series with the largest tag group acts as the “driver” that determines which raw timestamps are included in the alignment. All subsequent series are aligned to the driver’s raw timestamps using the interpolation configuration. After alignment, the resulting (x, y, z, …) tuples are bucketed into time windows and aggregated.

outputFormat OutputFormat

The output format of the response. Defaults to LEGACY (JSON).

bucketCount integer

The number of buckets to return in the response. Maximum is 10,000. Defaults to 1,000 if not specified.

interpolationConfiguration InterpolationConfiguration

Controls how the N input series are aligned at the raw point level when producing multivariate buckets. When present, the server may fill forward a series value from the most recent prior raw point (bounded by the interpolation radius). This alignment happens BEFORE bucketing, ensuring that aggregated values in each bucket are computed from temporally aligned raw tuples. When absent, the default interpolation configuration is used.

Single run. Expands to one grouping per data source attached to the run: asset-typed sources contribute one grouping per data scope on the asset; dataset-typed sources contribute one grouping per dataset.

Set type to "driverSeries".

driverSeries DriverSeries

​

Set type to "union".

union Union

​

applyDataScopeOffsets boolean

When true, dataset resolution applies each data scope’s persisted offset as a time shift, and the client must not pre-apply those offsets itself. When absent or false, scope offsets are left to the client, preserving behavior for legacy clients that inject equivalent timeShift nodes into the compute request. Read from the context in scope at resolution time.

resolveAssetsThroughDatasets boolean

When true, Dataset.asset, the asset-typed sources of Dataset.run, and asset or run search expand through each asset’s mirrored derived dataset instead of its data scopes. Branches then carry the dataset’s declared channel-search split tag keys in place of the reserved DATA_SCOPE tag, so callers must filter and group on those keys; the definition’s own time shifts apply regardless of applyDataScopeOffsets; and an asset with no mirrored dataset resolves to no data. When absent or false, assets expand from their data scopes as before.

sourceRid string (RID)

Optional RID identifying the resource that initiated this query (e.g. workbook/notebook RID, checklist RID, dataset RID). Used for observability only — trusted as-is, no permission checks are performed on this value.

requestId string (UUID)

Optional UUID to provide as a handle to selectively cancel the execution of this compute request.

Batch kill requests#

POST /compute/v2/compute/batch/kill

Best-effort cancellation of active compute requests. Each ID should be the request ID that the client originally passed when starting the request. A single request may correspond to one or more underlying operations, all of which will be cancelled.

Body

requestIds array of string (UUID)

​

Response

No content (HTTP 204).

Batch get request progress#

POST /compute/v2/compute/batch/progress

Returns a point-in-time snapshot of progress for the given active compute requests. Each ID should be the request ID that the client originally passed when starting the request. Intended to be polled (roughly once per second) for requests that have been running longer than the slow-query threshold.

A request with no active queries is not necessarily finished: its underlying queries may not have started yet, the request may be in a post-processing phase, or the request’s work may be executed somewhere that does not report progress — in which case it stays inactive for its entire duration. Clients should derive progress from the raw row counters and must not assume monotonicity, since totalRowsApprox can grow while a request runs.

Body

requestIds array of string (UUID)

Limited to 300 IDs per call.

Response

progressByRequestId map of string to RequestProgress

Contains an entry for every requested request ID.

Set type to "inProgress".

inProgress RequestInProgress

​

Fields of RequestInProgress
readRows integer (int64)

​

totalRowsApprox integer (int64)

May grow while a query runs as new sources to process become known.

Set type to "inactive".

Fields of QuotaIntervalUsage
durationSeconds integer (int64)

Length of the quota window in seconds.

currentWindow QuotaWindow

Bounds of the current quota window. Usage counters reset at the window’s end.

Fields of QuotaWindow
startTime string (date-time)

​

endTime string (date-time)

​

resources array of QuotaResourceUsage

Usage per limited resource. Resources without a configured limit are not reported.

Fields of QuotaResourceUsage
resource QuotaResourceType

​

Values of QuotaResourceType
READ_ROWS

​

READ_BYTES

​

QUERIES

​

ERRORS

​

EXECUTION_TIME

​

used number

Amount consumed within the current window, in the resource’s native unit (rows, bytes, query count, or seconds for EXECUTION_TIME).

limit number

The cap for this resource in this window.

Some points in the input had negative (or zero) x-values. Power and logarithmic curve fits do not allow negative (or zero) x-valued points.

400

CurveUnequalInputLength

The x and y inputs to fit a curve to do not have the same length.

400

CustomCurveFormulaMissingParameter

A custom curve fit declared a parameter (with an initial guess) that its formula never references. Every declared parameter must appear in the formula; otherwise it is an unconstrained degree of freedom for the solver. Remove the unused parameter or reference it in the formula.

400

CustomCurveFormulaMissingVariable

A custom curve fit declared a variable that its formula never references. The unused variable’s series would be fetched and aligned for nothing, so it almost certainly indicates a mistake in the formula. Remove the unused variable or reference it in the formula.

400

CustomCurveMultipleTimeVariables

A custom curve fit may declare at most one time variable; there is only one sample-timestamp axis for the formula to refer to.

The provided set must contain at least one element.

400

ExponentialCurveInputTooLarge

Due to limits in how numbers are represented by computers, exponential fits cannot be performed on data with x-values that are too large (> 650). This includes timestamp data based on the Time Unit parameter to the curve fit - e.g. 1 second at millisecond scale is too large, as it is 1000 milliseconds.

400

Not enough data points to estimate a sampling frequency for frequency-domain analysis. Try again with a larger time range.

400

FrequencyDomainWindowEmpty

The selected window for the frequency domain is empty. Try again with a larger time range.

400

MaxQuerySizeExceeded

The maximum query size was exceeded.

400

MemoryLimitExceeded

The query exceeded the memory limit. Try querying a smaller time range or fewer series.

400

MisalignedScatterPoints

No scatter points could be aligned for plotting. This typically means the input series do not have overlapping timestamps within the configured interpolation window.

400

MissingFunctionParameter

The requested module function could not be executed because a required parameter was not provided.

400

MissingModuleApplication

The requested module application could not be found. This may be because the reference is incorrect or the application is unavailable in the current execution context.

400

SelectPropertyMissingProperty

No resolved asset or run branch provides the selected property.

400

SelectPropertyWrongType

A resolved branch has the selected property, but its typed variant differs from the numeric or string type required by the series node.

400

SelectSeriesNameConflictsWithChannelFilter

A SelectSeries node provided both the name field and a NOMINAL_CHANNEL tag filter. Use the NOMINAL_CHANNEL filter alone to select channels.

400

SelectSeriesResolvedNoChannels

A channel selection (channel name plus tag filters) resolved to zero dataset channels for the requested scope and time range, so the series has nothing to read. Verify the channel exists in the dataset and that the tag filters match at least one channel over the requested range.

400

SelectTagsNotSubset

Select tags keys must be a subset of the tags available on the input series.

400

ServerOverloaded

The query was rejected because the compute backend is temporarily overloaded. This is a transient, load-shedding response that protects overall availability; the query itself is valid. Callers do not receive this error directly: the read path wraps it in a QoS unavailable response (503), so standard classic REST clients back off and retry automatically. The error type is retained as the 503’s cause for server-side logging and query_log correlation via queryId.

400

SignalFilterInvalidCutoffBand

Lower band cutoff frequency must be less than or equal to upper band cutoff frequency.

400

SignalFilterInvalidCutoffFrequency

Cutoff frequency must be less than half the sampling frequency.

400

400

SignalFilterNonPositiveCutoffFrequency

Cutoff frequency must be strictly positive.

400

SignalFilterNotEnoughData

Not enough data to apply the filter. Required data scales with filter order. Try again with a larger time range.

Too many literals provided in a literal node.

400

TooManyPoints

The number of points returned is greater than the max allowed. Try again with a smaller time range, or a larger resolution.

400

TooManyRanges

Ranges is greater than the max allowed (2000).

400

TooManyResamplePoints

The resample interval is too short and would produce more than the max points (10,000,000). Try again by specifying a larger interval.

400

TooManySearchResults

Asset or run search returned more matches than a single page allows. Refine the query or raise maxResults for the search frame so all matches fit in one page.

400

TooManySubrequests

Number of parameterized subrequests is greater than the max allowed (300).

400

TooManyValueMapRanges

A value map series contains too many range mappings.

400

TruncationNotSupportedForSeriesType

The requested series type does not support truncation for this compute request.

400

UdfExecutionLimitExceeded

A user-defined function exceeded its per-query execution limit while processing this query. Try querying a smaller time range, increasing the aggregation bucket size to reduce the number of UDF invocations, or simplifying the function’s per-row logic.

400

UdfMemoryLimitExceeded

A user-defined function exceeded its per-invocation memory limit.

400

UdfRuntimeError

A user-defined function panicked or aborted at runtime.

400

UnequalInputLength

The paired inputs for a calculation do not have the same length.

400

500

ConcurrentQueriesExceeded

There are too many concurrent queries running.

500

UdfNotRegistered

A native user-defined function was not registered on the when the query executed. This indicates an internal failure rather than invalid user input.

500

​

function NumericAggregationFunction required

​

groupByTags array of StringConstant

Tags to group by for the aggregation. If left empty, the tags to group by will be equivalent to those in the input series. If specified, the result will be grouped ONLY by the specified tags. The tags specified here MUST be a (non-strict) subset of the input series’s group by tags.

aggregateByAllGroupings boolean

This field’s purpose is to distinguish between the two flavors of groupByTags being empty. It has no effect when groupByTags is non-empty. When true and groupByTags is empty, aggregate across all series in the input. When false and groupByTags is empty, the result will be grouped by the same tags as the input series.

interpolationConfiguration InterpolationConfiguration deprecated

If provided, interpolates values at timestamps where the input series has values before aggregating. If not provided, only aggregates when timestamps match exactly (existing behavior). Deprecated: Setting interpolation on this node is deprecated.

AggregateUnderRangesSeries#

Aggregates the input series under the ranges in the provided ranges series, and outputs a new series with one point at the start of each range, where the value is the aggregation result. If a range has no points, no point will be produced for it. If a range has no start, the point produced for it will be at the start of the compute request range.

input NumericSeries required

AnchorAlignedDataset#

Aligns each anchored portion of the input dataset onto a common anchor timestamp while preserving grouping tags. Without a reference the selected anchor becomes timestamp zero, so the output is in a relative time domain; with a reference the anchors are aligned onto the referenced portion’s anchor and the output stays in the input’s absolute time domain. Currently run boundary, event, and range anchors are supported, and every storage-backed leaf of the input must resolve to run-backed branches.

input Dataset required

The dataset to align.

anchor DatasetAnchor required

Selects the timestamp each anchored portion of the input is aligned by.

reference AnchorReference

When present, each anchor is aligned onto the referenced anchor timestamp instead of onto timestamp zero, so output remains in the input’s absolute time domain and the referenced portion is unshifted. When absent, the selected anchor becomes timestamp zero.

AnchorReference#

Selects the anchor timestamp every other anchor is aligned onto.

Set type to the name of one of the other fields, and set only that field.

earliestAnchor EarliestAnchorReference

Aligns every anchor onto the earliest anchor resolved from the input, so the earliest-anchored run is unshifted and every other run shifts backwards onto it.

This field specifies the tags that the final output is grouped by. When you combine multiple channels, this list represents the superset of all group by keys used across every individual channel.

nextPageToken PageToken

Continuation token for this paged result. Can only be returned if paging was requested. To retrieve the next page, repeat the same request with this value as pageToken and keep the pageSize sign unchanged. Returned only when this response contains exactly abs(pageSize) points; the next response may still be empty if this page ended exactly at the result-set boundary. Empty means this response was short and there are no further points in the requested direction.

Asin#

Computes the arcsine of each value, returning radians.

x NumericSeries required

Input numeric series (values in [-1, 1]).

Asset#

Asset reference for Dataset.asset. The rid field accepts either a literal asset RID or a StringConstant reference resolved from Context.

additionalTags map of string to StringConstant deprecated

Deprecated: Use additionalTagFilters

additionalTagFilters TagFilters

Tags to filter the channel by, in addition to tag filters defined for a given Asset data scope. Throws on collisions with tag keys already defined for the given Asset data scope. Only returns points that match both sets of tag filters. For log series, include arg filters here in addition to tag filters.

tagsToGroupBy array of string deprecated

Deprecated: Use groupByTags instead. Throws if both tagsToGroupBy and groupByTags are specified.

groupByTags array of StringConstant

Tags that the channel should be grouped by. If this is non-empty a grouped result will be returned with an entry for each grouping. Only one of tagsToGroupBy and groupByTags should be specified.

CombinedDataset#

Combines multiple datasets into a single dataset by taking the union of all points from each input (akin to SQL {@code UNION ALL}). Duplicate timestamps are preserved rather than merged; callers that need aggregation should wrap the selected series downstream.

inputs array of Dataset

The datasets to combine.

CombineStructSeries#

Combines named input series into one struct-valued series. Each map key becomes a field name in the resulting struct; a downstream UDF receives the struct as a JSON object keyed by these names and parses it itself. Alignment uses the interpolation configuration before producing row-aligned values.

inputs map of string to Series

Input series keyed by struct field name.

defaultAlignmentStrategy Alignment

Default alignment strategy applied at every multi-input alignment boundary where no per-node alignment strategy is specified. When absent, falls back to the server default (driver-series alignment).

applyDataScopeOffsets boolean

When true, dataset resolution applies each data scope’s persisted offset as a time shift, and the client must not pre-apply those offsets itself. When absent or false, scope offsets are left to the client, preserving behavior for legacy clients that inject equivalent timeShift nodes into the compute request. Read from the context in scope at resolution time.

resolveAssetsThroughDatasets boolean

When true, Dataset.asset, the asset-typed sources of Dataset.run, and asset or run search expand through each asset’s mirrored derived dataset instead of its data scopes. Branches then carry the dataset’s declared channel-search split tag keys in place of the reserved DATA_SCOPE tag, so callers must filter and group on those keys; the definition’s own time shifts apply regardless of applyDataScopeOffsets; and an asset with no mirrored dataset resolves to no data. When absent or false, assets expand from their data scopes as before.

DimensionsDataset#

Injects one tag per dimension onto every series of the underlying dataset, valued from the asset or run the series belongs to. This makes resource metadata usable as a grouping, filtering and aggregation dimension with selectTags, tag predicates and groupByTags. Group by the dimension together with ASSET_RID (or RUN_RID) to keep each resource separate, or by the dimension alone to pivot so that resources sharing a value fall into one group.

Dimensions are only supported on asset and run branches. Any other branch, such as a saved dataset or a derived series from withSeries, gets the reserved value NOMINAL_ABSENT for every dimension. To group derived series by a dimension, apply withDimensions to the withSeries input instead, so that the series they are computed from carry the dimension tags. A dimension tag replaces a series tag with the same key.

input Dataset required

EnumAggregation#

Aggregates an input series using an enum aggregation operator. Rolling aggregation builders are not supported; only the group-by shape is accepted at resolution time.

Numeric1dArrayToStartOfIntervalSeries#

Snaps each point’s timestamp to the start of its enclosing fixed-size time bucket. Buckets are epoch-aligned: a point at timestamp t (nanoseconds) is rewritten to floor(t / window) * window. Values and tag groupings are preserved; aggregation of points that collide on the snapped timestamp is the responsibility of downstream nodes.

NumericAggregation#

Aggregates an input series using the given operator. The shape of the aggregation (rolling time window, rolling point-count window, or group by) is selected by the aggregation builder passed as input. The operator must be compatible with that builder’s series, producing a numeric output: count reduces a series of any type, whereas SUM requires a numeric series.

input AggregationBuilder required

The aggregation shape to apply the operator over: a rolling time window, a rolling point-count window, or a group-by.

operator NumericAggregationOperator required

The reduction applied to each window or group (e.g. sum, mean, percentile). Must be compatible with the input series, producing a numeric output: Count works on any input series, whereas reductions like Sum require a numeric series.

udf NumericAggregationUdf

​

NumericAggregationUdf#

A user-defined numeric aggregation. The aggregation builder controls grouping/windowing. Supported Rust entrypoints accept grouped value vectors, optionally with leading sample timestamps, and return either one numeric value or timestamped numeric point(s), e.g. fn rms(values: Vec<f64>) -> f64, fn energy(timestamp_ns: Vec<i64>, values: Vec<f64>) -> f64, fn first(timestamp_ns: Vec<i64>, values: Vec<f64>) -> (i64, f64), or fn passthrough(timestamp_ns: Vec<i64>, values: Vec<f64>) -> Vec<(i64, f64)>. The value vector’s element type follows the aggregated series: Vec<f64> for a numeric series, and Vec<String> for a categorical or struct series, where each struct row arrives as a JSON object. A UDF over a combined struct series may instead take one vector per named struct field it needs, e.g. fn mean_product(channel0: Vec<f64>, channel1: Vec<f64>) -> f64. Parameter names select the fields, so a subset of the struct’s fields in any order is accepted.

ValueDifferenceSeries#

Calculates the first discrete difference of the input series. For each point, computes the difference between the current value and the previous value (current - previous). The first point in the input series is omitted from the output since it has no previous point to compare against.

This is equivalent to pandas DataFrame.diff() with period=1. Useful for analyzing changes between consecutive data points in time series data, such as detecting value increases or decreases.

Example: For input values [1.0, 1.0, 2.0, 2.5, 1.8], the output would be [0.0, 1.0, 0.5, -0.7] at the corresponding timestamps (the first timestamp is omitted).

ZscoreSeries#

Computes the z-score for each series within a group-by family. For each group at each timestamp, the output is (value - mean) / stddev, where mean and stddev are computed across all groups in the family at that timestamp, using the interpolation configuration to align values across groups. When stddev is zero at a timestamp (e.g., all groups have the same value), that data point is excluded from the output. If groupByTags is empty, all groups in the input series will be considered as a single family. This node only produces meaningful results when the input has a group by.

input NumericSeries required

​

groupByTags array of StringConstant

Tags to group by for the normalization. If left empty, all groups in the input will be considered as a single family. Otherwise, inputs will be normalized separately across the groups specified by the tags.

interpolationConfiguration InterpolationConfiguration deprecated
