Aggregator Transformation in a Streaming Mapping

Aggregator Transformation in a Streaming Mapping

Streaming mappings have additional processing rules that do not apply to batch mappings.

Mapping Validation

Mapping validation fails in the following situations:
  • A streaming pipeline contains more than one Aggregator transformation.
  • A streaming pipeline contains an Aggregator transformation and a Rank transformation.
  • An Aggregator transformation is upstream from a Lookup transformation.
  • An Aggregator transformation is in the same pipeline as a Lookup transformation with an inequality condition.
