Can we also add a test scenario for the topic data migration? This also happens many time in the production, e.g. topic migration from large number of partitions to smaller number. Assume we are switching kafka topic from topicA to topicB: 0. Create both kafka topics: topicA(128 partitions) and topicB(64 partitions), the table is setup with topicA. For seamless, no downtime nor data loss migration: 1. Add Kafka topicB into the table stream conf, ensure it's existence but no data coming so far 2. Cut the kafka producer from topicA to topicB 3. Wait for topicA data persisted in the table 4. Remove topicA from the stream configs -- This is an automated message from the Apache Git Service.
