Rank Transformation in a Streaming Mapping

Rank 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 Rank transformation is in the same streaming pipeline as a passive Lookup transformation configured with an inequality lookup condition.
  • A Rank transformation is upstream from a Joiner transformation.
  • A streaming pipeline contains more than one Rank transformation.
  • A streaming pipeline contains an Aggregator transformation and a Rank transformation.
