On SOW Message Delete

AMPS provides a module to run an action when a message is deleted from a topic in the SOW.

The amps-action-on-sow-delete-message module monitors a topic for deletions from the SOW. The action runs once for each message that is deleted in the matching topic.

This action requires the following parameters:

Parameter	Description
Topic (required)	The name of the topic to monitor for messages. This parameter does not support regular expressions. The topic name must be either a SOW topic, a view, a conflated topic or a queue. There is no default for this parameter.
MessageType (required)	The message type of the topic to monitor for messages. There is no default for this parameter.

The module adds the following variables to the AMPS context:

Variable	Description
AMPS_TOPIC	The topic of the message that was deleted.
AMPS_DATA	The current data of the message.
AMPS_DATA_LENGTH	The length of the current data of the message, in bytes.
AMPS_CORRELATION_ID	The correlation ID set on the publish command, if one was set.
