Marcelo Vanzin resolved SPARK-25151. ------------------------------------ Fix Version/s: 3.0.0 Resolution: Fixed Issue resolved by pull request 22138 [https://github.com/apache/spark/pull/22138] > Apply Apache Commons Pool to KafkaDataConsumer > ---------------------------------------------- > > Key: SPARK-25151 > URL: https://issues.apache.org/jira/browse/SPARK-25151 > Project: Spark > Issue Type: Improvement > Components: Structured Streaming > Affects Versions: 3.0.0 > Reporter: Jungtaek Lim > Assignee: Jungtaek Lim > Priority: Major > Fix For: 3.0.0 > > > KafkaDataConsumer contains its own logic for caching InternalKafkaConsumer > which looks like can be simplified via applying Apache Commons Pool. Benefits > of applying Apache Commons Pool are following: > * We can get rid of synchronization of KafkaDataConsumer object while > acquiring and returning InternalKafkaConsumer. > * We can extract the feature of object pool to outside of the class, so that > the behaviors of the pool can be tested easily. Now it doesn't have detailed > tests and only covers reported issues. > * We can get various statistics for the object pool, and also be able to > enable JMX for the pool. -- This message was sent by Atlassian Jira (v8.3.2#803003) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
