Detailed Description

A set of input parameters for const.

Creates a monitor that watches for a single table modification event type (insert, update, or delete) on a particular table (identified by tableName) and forwards event notifications to subscribers via ZMQ. After this call completes, subscribe to the returned topicId on the ZMQ table monitor port (default 9002). Each time an operation of the given type 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 corresponds to the event and can be decoded using typeSchema. The monitor will continue to run (regardless of whether or not there are any subscribers) until deactivated with const.

For more information on table monitors, see Table Monitors.
