Sorter Transformation in a Streaming Mapping

Sorter 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 situation:
  • The Sorter transformation in a streaming mapping does not have an upstream Aggregator transformation.

General Guidelines

Consider the following general guidelines:
  • The mapping runs in complete output mode if it contains a Sorter transformation.
  • To maintain global sort order, ensure that the target is single-partitioned. Source can be single- or multi-partitioned.
