Khaireddine Rezgui commented on KAFKA-6535: ------------------------------------------- hi [~vvcephei], i have access to confluence wiki, but i haven't create menu, is it requere permision ? > Set default retention ms for Streams repartition topics to Long.MAX_VALUE > ------------------------------------------------------------------------- > > Key: KAFKA-6535 > URL: https://issues.apache.org/jira/browse/KAFKA-6535 > Project: Kafka > Issue Type: Improvement > Components: streams > Reporter: Guozhang Wang > Assignee: Khaireddine Rezgui > Priority: Major > Labels: needs-kip, newbie > > After KIP-220 / KIP-204, repartition topics in Streams are transient, so it > is better to set its default retention to infinity to allow any records be > pushed to it with old timestamps (think: bootstrapping, re-processing) and > just rely on the purging API to keeping its storage small. > More specifically, in {{RepartitionTopicConfig}} we have a few default > overrides for repartition topic configs, we should just add the override for > {{TopicConfig.RETENTION_MS_CONFIG}} to set it to Long.MAX_VALUE. This still > allows users to override themselves if they want via > {{StreamsConfig.TOPIC_PREFIX}}. We need to add unit test to verify this > update takes effect. > In addition to the code change, we also need to have doc changes in > streams/upgrade_guide.html specifying this default value change. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
