### Metadata

ParallelSimpleGather propagates metadata in both directions. The component does not change priorities of propagated metadata.

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. See the documentation of the SimpleGather component for more details about attributes and other component specific behavior.

This component belongs to 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
More details about usage of this component are available in the CloverETL Cluster documentation.

### Compatibility

#### 3.4

The component is available since 3.4.

#### 4.3.0-M2

In 4.3.0-M2, ClusterSimpleGather was renamed to ParallelSimpleGather.
