Types#

Abs#

Computes the absolute value of each point in the series.

x NumericSeries required: Input numeric series.

AbsoluteThreshold#

Threshold defined as a real number corresponding the unit of a series.

value DoubleConstant required: Allowed spread, in the series’ own unit.

AbsoluteTimestampSeries#

Replaces values in a series with the absolute timestamps.

input Series required
timeUnit 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 required: Input numeric series (values in [-1, 1]).

Add#

Adds two numeric series pointwise.

left NumericSeries required: Left-hand operand.
right 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 required
function 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 required
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
ranges RangeSeries required
operation 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.

driverSeries DriverSeries
union Union

AllowNegativeValues#

An empty JSON object, {}.

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.

AndSeries#

Combines two boolean series point-wise using logical AND, producing true where both inputs are true and false otherwise.

left BooleanSeries required
right BooleanSeries required

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.

Dimension#

A value derived per asset or run, injected as a tag.

tagKey StringConstant: The tag key to inject the value under. Defaults to the key derived by value.
value 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 required: The underlying dataset to tag.
dimensions array of Dimension: The dimensions to inject. Must not be empty, must have at most 10 entries, and every dimension must have a distinct tag key. A tag key must not be a ReservedTagKey, start with EVENT_LABEL_PREFIX:, or start with NOMINAL_.

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.

SelectSeries#

Selects series from a dataset (might contain multiple tag groupings). When name is provided, selects that single channel. When name is omitted, selection starts from all channels in the dataset scope; callers narrow the selection with a filterByTag predicate on the reserved NOMINAL_CHANNEL tag key and preserve per-channel identity in the response with selectTags. Providing both name and a NOMINAL_CHANNEL filter is rejected as an invalid request. Raw and derived channels can both be selected through the reserved tag filter.

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.
