Detailed Description

A set of output parameters for createTableMonitor(const CreateTableMonitorRequest&) const.

Creates a monitor that watches for new records inserted into a particular table (identified by tableName) and forwards copies to subscribers via ZMQ. After this call completes, subscribe to the returned topicId on the GPUdb ZMQ table monitor port (default 9002). Each time an insert operation on the table completes, a multipart message is published for that topic; the first part contains only the topic ID, and each subsequent part contains one binary-encoded Avro object that was inserted. The monitor will continue to run (regardless of whether or not there are any subscribers) until deactivated with clearTableMonitor(const ClearTableMonitorRequest&) const.
