Package org.nuxeo.ecm.core.bulk.computation

Class BulkScrollerComputation

java.lang.Object

org.nuxeo.lib.stream.computation.AbstractComputation

org.nuxeo.ecm.core.bulk.computation.BulkScrollerComputation

All Implemented Interfaces:

Computation

public class BulkScrollerComputation
extends AbstractComputation

Materializes the document set for a command if scroller is not external.

Inputs:

• i1: Reads a stream of BulkCommand sharded by action

Outputs:

• - "actionName": Writes BulkBucket into the action stream
• - "status": Writes BulkStatus into the action stream

Since:

10.2
