Jungtaek Lim resolved SPARK-38522. ---------------------------------- Fix Version/s: 3.4.0 Resolution: Fixed Issue resolved by pull request 35816 [https://github.com/apache/spark/pull/35816] > Strengthen the contract on iterator method in StateStore > -------------------------------------------------------- > > Key: SPARK-38522 > URL: https://issues.apache.org/jira/browse/SPARK-38522 > Project: Spark > Issue Type: Improvement > Components: Structured Streaming > Affects Versions: 3.3.0 > Reporter: Jungtaek Lim > Assignee: Jungtaek Lim > Priority: Major > Fix For: 3.4.0 > > > The root cause of SPARK-38320 was that the logic initialized the iterator > first, and performed some updates against state store, and iterated through > iterator expecting that all updates in between should be visible in iterator. > That is not guaranteed in RocksDB state store, and the contract of Java > ConcurrentHashMap which is used in HDFSBackedStateStore does not also > guarantee it. > It would be clearer if we update the contract to draw a line on behavioral > guarantee to callers so that callers don't get such expectation. -- This message was sent by Atlassian Jira (v8.20.1#820001) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
