Introspect query status

CREATE, DROP, and TERMINATE statements returns an object that indicates the current state of statement execution. A statement can be in one of the following states:

  • QUEUED, PARSING, EXECUTING: The statement was accepted by the server and is being processed.
  • SUCCESS: The statement was successfully processed.
  • ERROR: There was an error processing the statement. The statement was not executed.
  • TERMINATED: The query started by the statement was terminated. Only returned for CREATE STREAM|TABLE AS SELECT.

If a CREATE, DROP, or TERMINATE statement returns a command status with state QUEUED, PARSING, or EXECUTING from the /ksql endpoint, you can use the /status endpoint to poll the status of the command.
