Add Message ID

The Add Message ID processor adds a field containing a numeric identifier in to a process. Message IDs identify a packet of data, known as a message, as it passes through an OEDQ process.

Use

Add Message ID is used to add a numeric identifier to records. The message ID is unique within a data stream for records in batch processes and records created by real-time processes with single record inputs.

Note that, for a given data stream, this identifier will not be unique in the following circumstances:

The Message ID will not be unique for records originating from real-time processes or web services which have multi-record inputs. In this case, the message ID will be the same for all the records originating from a single request.
The Message ID will not be unique if records within a stream are split by the process. In this case, the message ID will be the same for all records derived from a single originating record.

Example
