Calculates the dependent output partitions and intermediate results from a single input partition.
Calculates the dependent output partitions and intermediate results from a single input partition.
- in
the input partition to process
- refs
All references that are required to process the input partition
- returns
All the impacted output partitions com.here.platform.data.processing.compiler.OutKey and intermediate data of type
Tfor this partition. It may contain more than one element per output key. compileOutFn will only be called for outKeys which have at least one intermediate value from this phase. Other outKeys will be automatically deleted.

Specifies the partitioner to use when querying the input catalogs. If no partitioner is provided, by returning None from this function, then the Executor uses the default partitioner.
- parallelism
The number of partitions the partitioner should partition the catalog into, this should match the parallelism of the Spark RDD containing the input partitions.

The optional input partitioner with the parallelism specified.
