Sorter Transformation Support on the Spark Engine

Sorter Transformation Support on the Spark Engine

Mapping validation fails when case sensitivity is disabled.
The Data Integration Service logs a warning and ignores the Sorter transformation in the following situations:
  • There is a type mismatch in between the target and the Sorter transformation sort keys.
  • The transformation contains sort keys that are not connected to the target.
  • The Write transformation is not configured to maintain row order.
  • The transformation is not directly upstream from the Write transformation.
The Data Integration Service treats null values as low even if you configure the transformation to treat null values as high.

Data Cache Optimization

You cannot optimize the sorter cache to store data using variable length.
