Joiner Transformation in a Streaming Mapping

Joiner 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 Joiner transformation is downstream from an Aggregator transformation.
  • A Joiner transformation is downstream from a Rank transformation.
  • A streaming pipeline contains more than one Joiner transformation.
  • A Joiner transformation joins data from streaming and non-streaming pipelines.

General Guidelines

To specify a join condition, select the TIME_RANGE function from the Advanced condition type on the Join tab and enter a join condition expression. The TIME_RANGE function determines the time range for the streaming events to be joined.
