At least one connected input port and at least one connected output port are required.

Metadata

SimpleGather propagates metadata in both directions. SimpleGather does not change metadata priorities.
SimpleGather has no metadata template.
Input ports must have the same metadata. Metadata name and field names may differ but the field datatypes must correspond to each other.
Output ports must have the same metadata. Metadata name and field names may differ but the field datatypes must correspond to each other.

Details

The order of output records is unpredictable. Only the order of records coming from the single port is preserved.
SimpleGather receives data records through one or more input ports. SimpleGather gathers (demultiplexes) all records as fast as possible and sends them all to all output ports.

If you need a component merging input records and preserving the order, use Concatenate or Merge.
