ParallelSimpleGather has no metadata templates.

ParallelSimpleGather does not require any specific metadata fields.

Details

ParallelSimpleGather gathers data records from multiple CloverETL Cluster workers.

The algorithm of this component is derived from the regular SimpleGather component. For more details about attributes and other component specific behavior, see the documentation of the SimpleGather component.

This component belongs to a group of cluster components that allows the change from a multiple-workers allocation to a single-worker allocation. So the allocation of the component preceding the ParallelSimpleGather component can provide multiple workers. The allocation of the component following the ParallelSimpleGather component has to provide a single worker.

[Note]Note

For more information about this component, see the CloverETL Cluster documentation (part of CloverETL Server documentation).
