Matthias J. Sax created KAFKA-6729: -------------------------------------- Summary: KTable should use user source topics if possible and not create changelog topic Key: KAFKA-6729 URL: https://issues.apache.org/jira/browse/KAFKA-6729 Project: Kafka Issue Type: Bug Components: streams Affects Versions: 1.0.0 Reporter: Matthias J. Sax Fix For: 1.2.0
With KIP-182 we reworked Streams API largely and introduced a regression into 1.0 code base. If a KTable is populated from a source topic, ie, StreamsBuilder.table() -- the KTable does create its own changelog topic. However, in older releases (0.11 or older), we don't create a changelog topic but use the user specified source topic instead. We want to reintroduce this optimization to reduce the load (storage and write) on the broker side for this case. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
