### Short Description

ParallelLoadBalancingPartition distributes incoming data records among different CloverETL Cluster workers. The algorithm of the component is derived from the regular LoadBalancingPartition component.

Component | Same input metadata | Sorted inputs | Inputs | Outputs | Java | CTL | Auto-propagated metadata

### Metadata

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

ParallelLoadBalancingPartition has no metadata template.

ParallelLoadBalancingPartition does not require any specific metadata fields.

### Details

ParallelLoadBalancingPartition distributes incoming data records among different CloverETL Cluster workers.

The algorithm of this component is derived from the regular LoadBalancingPartition component. See the documentation of the LoadBalancingPartition 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 single-worker allocation to a multiple-worker allocation. So the allocation of the component preceding the ParallelLoadBalancingPartition component has to provide just a single worker. The allocation of the component following the ParallelLoadBalancingPartition component can provide multiple workers.

| Note
More details about usage of this component are available in the CloverETL Cluster documentation.

### Compatibility

#### 3.4

The component is available since version 3.4.

#### 4.3.0-M2

In 4.3.0-M2, ClusterLoadBalancingPartition was renamed to ParallelLoadBalancingPartition.
