v0.84

Sources and sinks

• Breaking change. Deprecate the SIZE option for sources and sinks, which transparently created a (linked) cluster to maintain the object. Use the IN CLUSTER clause to create a source or sink in a specific a cluster. If you omit the clause altogether, the object will be created in the active cluster for the session.

New syntax

  --Create the object in a specific cluster
  CREATE SOURCE json_source
  IN CLUSTER some_cluster
  FROM KAFKA CONNECTION kafka_connection (TOPIC 'ch_anges')
  FORMAT JSON;

  --Create the object in the active cluster
  CREATE SOURCE json_source
  FROM KAFKA CONNECTION kafka_connection (TOPIC 'ch_anges')
  FORMAT JSON;

Deprecated syntax

  --Create the object in a dedicated (linked) cluster
  CREATE SOURCE json_source
  FROM KAFKA CONNECTION kafka_connection (TOPIC 'ch_anges')
  FORMAT JSON
  WITH (SIZE = '3xsmall');

• Make timeouts (transaction.timeout.ms) configurable for Kafka sinks. Default: 60000ms.
