DROP STREAM statement in ksqlDB for Confluent Platform

Synopsis

DROP STREAM [IF EXISTS] stream_name [DELETE TOPIC];

Description

Drops an existing stream.

If the DELETE TOPIC clause is present, the stream’s source topic is marked for deletion. If the topic format is AVRO, PROTOBUF, or JSON_SR, the corresponding schema is deleted. Topic deletion is asynchronous, and actual removal from brokers may take some time to complete.

Note

DELETE TOPIC will not necessarily work if your Kafka cluster is configured to create topics automatically with auto.create.topics.enable=true. You should check after a few minutes to ensure that the topic was deleted.

If the IF EXISTS clause is present, the statement doesn’t fail if the stream doesn’t exist.
