SyntheticDataSource

Helper for generating arbitrary data for a stream. Can be used to easily simulate a lot of load without needing actual data. Just change the scheme to be synthetic:, for example:

synthetic://host/api/v1/graph?q=name,sps,:eq,(,nf.cluster,),:by

The following URL parameters can be added to control the data volume:

• numStepIntervals: how many time intervals to generate data. The source stream will stop once it has reached that amount.

• inputDataSize: number of input data points to generate for each data expr.

• outputDataSize: number of output data points to generate for each grouped data expr.
