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.

- def compileOutFn(outKey: OutKey, intermediate: Iterable[T]): Map[OutKey, Payload]
Compiles a single output partition.
Compiles a single output partition.
- outKey
the key of the output partition to generate
- intermediate
non-empty scala.Iterable of intermediate data as provided by compileInFn which is required to compile the output partition. This collection will have multiple entries of the same value in case the same value was returned for this outKey by multiple compileInFn executions (for different input keys). outKeys which do not have any intermediate values assigned from the compileInFn calls get deleted automatically.
- returns
output keys and their com.here.platform.data.processing.blobstore.Payload for each partition that contains data. Any old data for keys returned by compileOutMapping but not returned here will be automatically deleted from the catalog.

- def compileOutMapping(outKey: OutKey): Set[OutKey]
Defines which output keys the compile out function will generate for a given output key of the intermediate data.
Defines which output keys the compile out function will generate for a given output key of the intermediate data.
- outKey
the output key in the intermediate data
- returns
Set of output keys that will be generated. Usually should contain outKey as well, unless the compileOutFn will not generate output with that key.

Specifies the partitioner to use when querying the input catalogs.
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.
- returns

- def preservesPartitioning: Boolean
Defines if all output keys generated by compileOutMapping are in the same Spark partition as the input parameter outKey.
Defines if all output keys generated by compileOutMapping are in the same Spark partition as the input parameter outKey. This can be guaranteed by using a com.here.platform.data.processing.spark.partitioner.PartitionNamePartitioner and in this case true should be returned
When this is set to true the result of compileOutFn will not be repartitioned, allowing a common stage with the upload functionality of the driver task.
