Create Table Monitor
Creates a monitor that watches for new records inserted into a particular table (identified by input parameter table_name) and forwards copies to subscribers via ZMQ. After this call completes, subscribe to the returned output parameter topic_id on the 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 Clear Table Monitor.
