Sequence Generator Transformation in the Hadoop Environment
The Sequence Generator transformation processing in the Hadoop environment depends on the engine that runs the transformation.
The Sequence Generator transformation is not supported on the Hive engine.
Sequence Generator Transformation Support on the Blaze Engine
A mapping with a Sequence Generator transformation consumes significant resources when the following conditions are true:
- •You set the Maintain Row Order property on the transformation to true.
- •The mapping runs in a single partition.
Sequence Generator Transformation Support on the Spark Engine
The Sequence Generator transformation does not maintain row order in output data. If you enable the Maintain Row Order property on the transformation, the Data Integration Service ignores the property.
