These components are dedicated for data flow management when using Data Partitioning or in CloverETL Cluster environment.
Table 59.1. Data Partitioning Components Comparison
Component | Same input metadata | Sorted inputs | Inputs | Outputs | Java | CTL | Auto-propagated metadata |
---|---|---|---|---|---|---|---|
ParallelPartition | 1 | 1 [1] | [2] | [2] | |||
ParallelLoadBalancingPartition | 1 | 1 [1] | |||||
ParallelSimpleGather | 1 [3] | 1 | |||||
ParallelMerge | 1 [3] | 1 | |||||
ParallelRepartition | 1 [3] | 1 [1] | [2] | [2] | |||
[1] The single output port represents multiple virtual output ports. [2] ParallelPartition and ParallelRepartition can use either the transformation or two other attributes (Ranges or Partition key). [3] The single input port represents multiple virtual input ports. |
