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`. **saved** Set `type` to `"saved"`. `saved` [`SavedDataset`](https://dev.nominal.io/api/rest/compute-service.md#saveddataset) : ​ **search** Set `type` to `"search"`. `search` [`SearchDataset`](https://dev.nominal.io/api/rest/compute-service.md#searchdataset) : ​ **combine** Set `type` to `"combine"`. `combine` [`CombinedDataset`](https://dev.nominal.io/api/rest/compute-service.md#combineddataset) : ​ **tag** Set `type` to `"tag"`. `tag` [`TaggedDataset`](https://dev.nominal.io/api/rest/compute-service.md#taggeddataset) : ​ **filter** Set `type` to `"filter"`. `filter` [`FilteredDataset`](https://dev.nominal.io/api/rest/compute-service.md#filtereddataset) : ​ **timeShift** Set `type` to `"timeShift"`. `timeShift` [`TimeShiftedDataset`](https://dev.nominal.io/api/rest/compute-service.md#timeshifteddataset) : ​ **alignByAnchor** Set `type` to `"alignByAnchor"`. `alignByAnchor` [`AnchorAlignedDataset`](https://dev.nominal.io/api/rest/compute-service.md#anchoraligneddataset) : ​ **withSeries** Set `type` to `"withSeries"`. `withSeries` [`WithSeriesDataset`](https://dev.nominal.io/api/rest/compute-service.md#withseriesdataset) : ​ **dropSeries** Set `type` to `"dropSeries"`. `dropSeries` [`DropSeriesDataset`](https://dev.nominal.io/api/rest/compute-service.md#dropseriesdataset) : ​ **reference** Set `type` to `"reference"`. `reference` [`DatasetReference`](https://dev.nominal.io/api/rest/compute-service.md#datasetreference) : ​ **withDimensions** Set `type` to `"withDimensions"`. `withDimensions` [`DimensionsDataset`](https://dev.nominal.io/api/rest/compute-service.md#dimensionsdataset) : ​ `defaultFillStrategy` [`FillStrategy`](https://dev.nominal.io/api/rest/compute-service.md#fillstrategy) : Default fill strategy applied at every multi-input alignment boundary where no per-node interpolationConfiguration is specified.

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.

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`](https://dev.nominal.io/api/rest/compute-service.md#outputformat) : The output format of the response.

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.

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`](https://dev.nominal.io/api/rest/compute-service.md#parameterizedcontext) required : Specifies how certain variables should be parameterized.

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).

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.

Each error’s `errorName` is `Compute:` followed by its name below. | Status | Name | Notes | | --- | --- | --- | | 400 | `CannotAggregateEnumPlot` | | | 400 | `CannotCompileRegexp` | The regular expression could not be compiled. | | 400 | `ChannelHasWrongType` | | | 400 | `ComputationTooComplex` | Computation too complex. Try reducing the number of channels, computations, or tags. | | 400 | `ConverterInputUnitNotFound` | A unit could not be found for the input series, or it did not exist in the unit system. The conversion could not be computed. | | 400 | `ConverterOutputUnitNotFound` | The output unit symbol could not be found in the unit system. The conversion could not be computed. | | 400 | `CurveInvalidNegativeInputs` | 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. | | 400 | `DerivedSeriesHasWrongType` | | | 400 | `DuplicateTimestamp` | | | 400 | `EmptyInput` | At least one input must be provided. | | 400 | `EmptyPath` | Specified path cannot be empty. | | 400 | `EmptySet` | 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 | `FrequencyDomainNotEnoughData` | 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 | `FrequencyDomainWindowTooLarge` | The selected window for the frequency domain is too large. Try again with a smaller time range. | | 400 | `GranularityMismatch` | Some operations that require matching granularity did not have matching granularity. | | 400 | `GroupByMissingTag` | Attempted to group by a tag that does not exist. | | 400 | `GroupByTagsNotSubset` | Group by tags must be equal, or one set must be a subset of the other. | | 400 | `GroupBysNotSupportedForQuery` | Group by queries are not supported for the compute node supplied | | 400 | `InvalidBitOperation` | The bit operation is invalid due to the index or operand being out of range. Valid range - [0, 63]. | | 400 | `InvalidExpression` | | | 400 | `InvalidFieldName` | Struct field names cannot contain ‘.’ | | 400 | `InvalidLiteralRange` | The starting timestamp of a range cannot be greater than or equal to the end timestamp. At least one of start and end timestamps must be present. Only the first range when sorted may omit the start, and only the last may omit the end. | | 400 | `InvalidNumericAggregations` | Numeric aggregations can only be specified on numeric series requests. | | 400 | `InvalidNumericOutputFields` | Numeric output fields can only be specified on Arrow format numeric series requests. At least one field must be specified. | | 400 | `InvalidPlotType` | | | 400 | `InvalidRangeNodeStartAfterViewRange` | The compute node was given a starting timestamp after the end of the view range window. | | 400 | `InvalidRefpropInputCount` | REFPROP requires exactly two input series. | | 400 | `InvalidSeriesLocator` | | | 400 | `InvalidTagFilterConfiguration` | Invalid tag filter configuration was provided. | | 400 | `InvalidTimeUnit` | The time unit associated with the series is incompatible with the current transform. | | 400 | `InvalidUdfSource` | The Rust UDF source failed validation or compilation. | | 400 | `InvalidValueMap` | Range end must be greater than range start. Range start may only be undefined if in the first range, or the prior end is defined and less. Range end may only be undefined if in the last range, or the next start is defined and greater. Ranges must be in increasing order. | | 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 | `MissingModuleFunction` | The requested module function could not be found. This may be because the reference is incorrect or the function is unavailable in the current execution context. | | 400 | `MissingModuleVariable` | | | 400 | `MissingVariable` | | | 400 | `NonPositiveDuration` | Duration must be strictly positive. | | 400 | `NonPositiveResampleInterval` | The resample interval must be strictly positive. | | 400 | `NotEnoughPointsForCurve` | There were not enough points to fit the curve requested. | | 400 | `OverlappingLiteralRanges` | Ranges cannot overlap. Only the first range when sorted may omit the start, and only the last may omit the end. | | 400 | `QueryRangeTooLarge` | The requested time range is too large. Try again with a smaller time range. | | 400 | `RefpropInputTooLarge` | The number of points in the REFPROP inputs is too large. | | 400 | `RefpropOutputPropertyIsInput` | The output property cannot be one of the input properties for REFPROP. | | 400 | `RequestCancelled` | The compute request was cancelled by the user. | | 400 | `RequestedRowsLimitExceeded` | The maximum number of points that can be returned is 10,000. | | 400 | `ResampleDefaultValueTypeMismatchesSeriesType` | The default value provided for resampling does not match the type of the series being resampled. | | 400 | `ResolutionIntervalTooSmallForRange` | | | 400 | `RowLimitExceeded` | The query exceeded that limit for number of rows returned. For the query to complete, either zoom in or downsample. | | 400 | `S3ObjectStorageRateLimited` | S3 rejected the request with a TooManyRequests error. Try again with a smaller time range, fewer series, or after a short wait. | | 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 | `SignalFilterInvalidOrder` | Order must be positive even numbers for bidirectional filters. Bidirectional filters are applied once forwards and once backwards, effectively doubling order. Doubled again for bandpass/bandstop filters, requiring a multiple of 4 for filter order. | | 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. | | 400 | `SourceBlocked` | Queries from this source are temporarily blocked. | | 400 | `SpectrogramUnsupportedInput` | The spectrogram input reads from more than one data source or uses an operation spectrograms do not support. | | 400 | `TimeoutExceeded` | The query timed out. Try querying a smaller time range or fewer series. | | 400 | `TooFewInputs` | The operation requires more input series than were provided. | | 400 | `TooManyBuckets` | The number of buckets returned is greater than the max allowed (1000). Try again by specifying a larger bucket width or fewer bucket counts. | | 400 | `TooManyCategories` | An enum series has more categories than the max allowed. | | 400 | `TooManyEvents` | Number of events is greater than the max allowed (1000). | | 400 | `TooManyFrequencyBins` | The number of one-sided frequency bins exceeds the maximum allowed. Reduce nfft in transform settings to produce fewer bins. | | 400 | `TooManyLiterals` | 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 | `UnitConversionInvalid` | The unit conversion could not be computed because the input unit cannot be converted to the output unit. | | 400 | `UnknownBuiltinConstant` | | | 400 | `UnsupportedRefpropProperty` | The specified REFPROP property is not supported or not available in the current configuration. | | 400 | `UnsupportedRefpropSubstance` | The specified REFPROP substance is not supported or not available in the current configuration. | | 400 | `VariableHasWrongType` | | | 403 | `NotAuthorized` | | | 500 | `ComputeBackendUnavailable` | The compute backend was temporarily unavailable before the query could be submitted. Retry the request after a short delay. | | 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 | `UnexpectedTimeout` | An unexpected timeout occurred when executing a query. This indicates an internal error where the query may have succeeded but the response did not reach the client. | Each error’s `errorName` is `ExternalDatabase:` followed by its name below. | Status | Name | Notes | | --- | --- | --- | | 400 | `ExternalDatabaseGatewayTimeout` | A gateway timeout was encountered while trying to fetch data from the external database. | | 400 | `ExternalDatabaseRateLimitExceeded` | The external database rate limit was exceeded. | | 500 | `ExternalDatabaseBadGateway` | A bad gateway result was encountered while trying to fetch data from the external database. | | 500 | `ExternalDatabaseSocketTimeout` | A socket timeout was encountered while trying to fetch data from the external database. | ## Types ### Abs Computes the absolute value of each point in the series. `x` [`NumericSeries`](https://dev.nominal.io/api/rest/compute-service.md#numericseries) required : Input numeric series. ### AbsoluteThreshold Threshold defined as a real number corresponding the unit of a series. `value` [`DoubleConstant`](https://dev.nominal.io/api/rest/compute-service.md#doubleconstant) required : Allowed spread, in the series’ own unit. ### AbsoluteTimestampSeries Replaces values in a series with the absolute timestamps. `input` [`Series`](https://dev.nominal.io/api/rest/compute-service.md#series) required : ​ `timeUnit` [`TimeUnit`](https://dev.nominal.io/api/rest/compute-service.md#timeunit) required : The time unit used to define the output values. Throws an error if nanosecond or finer. ### Acos Computes the arccosine of each value, returning radians. `x` [`NumericSeries`](https://dev.nominal.io/api/rest/compute-service.md#numericseries) required : Input numeric series (values in [-1, 1]). ### Add Adds two numeric series pointwise. `left` [`NumericSeries`](https://dev.nominal.io/api/rest/compute-service.md#numericseries) required : Left-hand operand. `right` [`NumericSeries`](https://dev.nominal.io/api/rest/compute-service.md#numericseries) required : Right-hand operand. ### AfterPersistenceWindow The first point in the output range will be the first point after the condition has been true for the min duration and min points. An empty JSON object, `{}`. ### AggregateEnumSeries Aggregates values with duplicate timestamps in the input series values into a single value using the specified aggregation function. `input` [`EnumSeries`](https://dev.nominal.io/api/rest/compute-service.md#enumseries) required : ​ `function` [`EnumAggregationFunction`](https://dev.nominal.io/api/rest/compute-service.md#enumaggregationfunction) required : ​ ### AggregateNumericSeries DEPRECATED. Use a dedicated group-by-and-aggregate nodes instead. Aggregates values with duplicate timestamps in the input series values into a single value using the specified aggregation function. `input` [`NumericSeries`](https://dev.nominal.io/api/rest/compute-service.md#numericseries) required : ​ `function` [`NumericAggregationFunction`](https://dev.nominal.io/api/rest/compute-service.md#numericaggregationfunction) required : ​ `groupByTags` array of [`StringConstant`](https://dev.nominal.io/api/rest/compute-service.md#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`](https://dev.nominal.io/api/rest/compute-service.md#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`](https://dev.nominal.io/api/rest/compute-service.md#numericseries) required : ​ `ranges` [`RangeSeries`](https://dev.nominal.io/api/rest/compute-service.md#rangeseries) required : ​ `operation` [`NumericAggregationFunction`](https://dev.nominal.io/api/rest/compute-service.md#numericaggregationfunction) required deprecated : **Deprecated:** Use a dedicated group-by-and-aggregate node instead (coming in a follow-up PR). This field is retained as required for backwards compatibility with existing callers. ### AggregationBuilder Set `type` to the name of one of the other fields, and set only that field. `rollingTime` [`RollingTimeAggregationBuilder`](https://dev.nominal.io/api/rest/compute-service.md#rollingtimeaggregationbuilder) : ​ `rollingPoints` [`RollingPointsAggregationBuilder`](https://dev.nominal.io/api/rest/compute-service.md#rollingpointsaggregationbuilder) : ​ `groupBy` [`GroupByAggregationBuilder`](https://dev.nominal.io/api/rest/compute-service.md#groupbyaggregationbuilder) : ​ ### Alignment Specifies how to set the timestamp grid for multi-input operations.

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`](https://dev.nominal.io/api/rest/compute-service.md#dataset) required : The dataset to align. `anchor` [`DatasetAnchor`](https://dev.nominal.io/api/rest/compute-service.md#datasetanchor) required : Selects the timestamp each anchored portion of the input is aligned by. `reference` [`AnchorReference`](https://dev.nominal.io/api/rest/compute-service.md#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`](https://dev.nominal.io/api/rest/compute-service.md#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. ### AndSeries Combines two boolean series point-wise using logical AND, producing true where both inputs are true and false otherwise. `left` [`BooleanSeries`](https://dev.nominal.io/api/rest/compute-service.md#booleanseries) required : ​ `right` [`BooleanSeries`](https://dev.nominal.io/api/rest/compute-service.md#booleanseries) required : ​ ### ApproximateThresholdOperator `EQUAL_TO` : ​ `NOT_EQUAL_TO` : ​ ### ApproximateThresholdRanges Produces a list of ranges for which the threshold condition is satisfied. `input` [`NumericSeries`](https://dev.nominal.io/api/rest/compute-service.md#numericseries) required : ​ `threshold` [`DoubleConstant`](https://dev.nominal.io/api/rest/compute-service.md#doubleconstant) required : ​ `tolerance` [`DoubleConstant`](https://dev.nominal.io/api/rest/compute-service.md#doubleconstant) required : ​ `operator` [`ApproximateThresholdOperator`](https://dev.nominal.io/api/rest/compute-service.md#approximatethresholdoperator) required : ​ `persistenceWindowConfiguration` [`PersistenceWindowConfiguration`](https://dev.nominal.io/api/rest/compute-service.md#persistencewindowconfiguration) : ​ ### ArithmeticSeries `inputs` map of `LocalVariableName` to [`NumericSeries`](https://dev.nominal.io/api/rest/compute-service.md#numericseries) : ​ `expression` string required : ​ `interpolationConfiguration` [`InterpolationConfiguration`](https://dev.nominal.io/api/rest/compute-service.md#interpolationconfiguration) deprecated : Defaults to forward fill interpolation with a 1s interpolation radius **Deprecated:** Setting interpolation on this node is deprecated. ### ArraySeries Set `type` to the name of one of the other fields, and set only that field. `numeric1d` [`Numeric1dArraySeries`](https://dev.nominal.io/api/rest/compute-service.md#numeric1darrayseries) : ​ `enum1d` [`Enum1dArraySeries`](https://dev.nominal.io/api/rest/compute-service.md#enum1darrayseries) : ​ ### ArrowArrayPlot Set `type` to the name of one of the other fields, and set only that field. `bucketedNumeric` [`BucketedNumericArrayPlot`](https://dev.nominal.io/api/rest/compute-service.md#bucketednumericarrayplot) : ​ `bucketedEnum` [`BucketedEnumArrayPlot`](https://dev.nominal.io/api/rest/compute-service.md#bucketedenumarrayplot) : ​ ### ArrowPlot A generic Arrow IPC plot response. Used for all Arrow-serialized plot types (numeric, bucketed numeric, enum, bucketed enum, struct, bucketed struct, full resolution, and bucketed multivariate). `arrowBinary` string (base64) required : The raw binary containing an Arrow IPC stream. `groupByKeys` array of string : 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`](https://dev.nominal.io/api/rest/compute-service.md#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`](https://dev.nominal.io/api/rest/compute-service.md#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`. `rid` [`StringConstant`](https://dev.nominal.io/api/rest/compute-service.md#stringconstant) required : Resource identifier of an asset ### AssetChannel `assetRid` [`StringConstant`](https://dev.nominal.io/api/rest/compute-service.md#stringconstant) required : ​ `dataScopeName` [`StringConstant`](https://dev.nominal.io/api/rest/compute-service.md#stringconstant) required : Used to disambiguate when multiple data scopes within this asset contain channels with the same name. `channel` [`StringConstant`](https://dev.nominal.io/api/rest/compute-service.md#stringconstant) required : ​ `additionalTags` map of string to [`StringConstant`](https://dev.nominal.io/api/rest/compute-service.md#stringconstant) deprecated : **Deprecated:** Use additionalTagFilters `additionalTagFilters` [`TagFilters`](https://dev.nominal.io/api/rest/compute-service.md#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.

Set `type` to the name of one of the other fields, and set only that field. `function` [`FunctionDerivedSeries`](https://dev.nominal.io/api/rest/compute-service.md#functionderivedseries) : ​ ### DetrendType The type of detrending to apply to the signal. When absent, will default to the detrend behavior for that function. `CONSTANT` : Removes the mean value of the signal. `LINEAR` : Removes a best-fit linear trend from the signal. `NO_OP` : Does not perform any detrending. ### Dimension A value derived per asset or run, injected as a tag. `tagKey` [`StringConstant`](https://dev.nominal.io/api/rest/compute-service.md#stringconstant) : The tag key to inject the value under. Defaults to the key derived by `value`. `value` [`DimensionValue`](https://dev.nominal.io/api/rest/compute-service.md#dimensionvalue) required : The value to inject. ### 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`](https://dev.nominal.io/api/rest/compute-service.md#dataset) required : The underlying dataset to tag. `dimensions` array of [`Dimension`](https://dev.nominal.io/api/rest/compute-service.md#dimension) : The dimensions to inject.

An empty JSON object, `{}`. ### DriverSeries3d `X` : ​ `Y` : ​ `Z` : ​ ### DropSeriesDataset Removes series from the base dataset by name: raw and derived series alike are no longer selectable under those names. Dropping a name absent from `input` has no effect. Combined with `WithSeriesDataset`, which can expose a series under another name, this renames a series: `dropSeries(withSeries(input, [newName = select(oldName)]), [oldName])`. `input` [`Dataset`](https://dev.nominal.io/api/rest/compute-service.md#dataset) required : The base dataset to drop series from. `names` array of [`StringConstant`](https://dev.nominal.io/api/rest/compute-service.md#stringconstant) : Names of the series to drop. ### DurationAdd The sum of two durations. `left` [`compute.api.Duration`](https://dev.nominal.io/api/rest/compute-service.md#compute-api-duration) required : First duration. `right` [`compute.api.Duration`](https://dev.nominal.io/api/rest/compute-service.md#compute-api-duration) required : Second duration. ### DurationConstant A duration constant that can be a literal value or a named variable reference.

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. `input` [`Enum1dArraySeries`](https://dev.nominal.io/api/rest/compute-service.md#enum1darrayseries) required : ​ `window` [`compute.api.Duration`](https://dev.nominal.io/api/rest/compute-service.md#compute-api-duration) 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. `Min` and `Max` require a categorical input series. `Udf` also accepts a numeric input, which reaches the function as `Vec`; a categorical input reaches it as `Vec`. `input` [`AggregationBuilder`](https://dev.nominal.io/api/rest/compute-service.md#aggregationbuilder) required : The aggregation shape to apply the operator over. Only the group-by shape is supported; rolling builders are rejected at resolution time. The Python `enum_aggregation(...)` sugar form is categorical-only.

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`, `fn energy(timestamp_ns: Vec, values: Vec) -> f64`, `fn first(timestamp_ns: Vec, values: Vec) -> (i64, f64)`, or `fn passthrough(timestamp_ns: Vec, values: Vec) -> Vec<(i64, f64)>`. The value vector’s element type follows the aggregated series: `Vec` for a numeric series, and `Vec` 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, channel1: Vec) -> f64`.

The algorithm preserves the first and last points, partitions the remaining input points based on the requested output count, and selects points that preserve the visual shape of the series. Results are selected input timestamp/value points, not fixed-width bucket aggregate rows. `input` [`NumericSeries`](https://dev.nominal.io/api/rest/compute-service.md#numericseries) required : ​ `maxPointsToReturn` [`IntegerConstant`](https://dev.nominal.io/api/rest/compute-service.md#integerconstant) required : Maximum number of selected points to return.

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). `input` [`NumericSeries`](https://dev.nominal.io/api/rest/compute-service.md#numericseries) required : ​ `negativeValuesConfiguration` [`NegativeValueConfiguration`](https://dev.nominal.io/api/rest/compute-service.md#negativevalueconfiguration) : Defines the strategy for handling negative output values.

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`](https://dev.nominal.io/api/rest/compute-service.md#numericseries) required : ​ `groupByTags` array of [`StringConstant`](https://dev.nominal.io/api/rest/compute-service.md#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`](https://dev.nominal.io/api/rest/compute-service.md#interpolationconfiguration) deprecated : Configuration for aligning values across groups at each timestamp.
