Aggregation Properties

The aggregation process is specified by an aggregation type consisting of the following list of properties:

Name Description

Name	Description
`id`	Aggregation ID
`groupingFields`	List of signal field names
`signalTypes`	List of signal types
`aggregator`	Symbolic name of the aggregator implementation
`selectQuery`	Query string, default `:`
`sort`	Ordering of aggregated signals
`timeRange`	String specifying time range, e.g., `[* TO NOW]`
`outputPipeline`	Pipeline ID for processing aggregated events
`outputCollection`	Output collection name
`rollupPipeline`	Rollup pipeline ID
`rollupAggregator`	Name of the aggregator implementation used for rollups
`sourceRemove`	Boolean, default is false
`sourceCatchup`	Boolean, default is true
`outputRollup`	Boolean, default is true
`aggregates`	List of aggregation functions
`params`	Arbitrary parameters to be used by specific aggregator implementations
