Michael Armbrust updated SPARK-17829: ------------------------------------- Issue Type: Improvement (was: Sub-task) Parent: (was: SPARK-8360) > Stable format for offset log > ---------------------------- > > Key: SPARK-17829 > URL: https://issues.apache.org/jira/browse/SPARK-17829 > Project: Spark > Issue Type: Improvement > Components: Structured Streaming > Reporter: Michael Armbrust > Assignee: Tyson Condie > > Currently we use java serialization for the WAL that stores the offsets > contained in each batch. This has two main issues: > - It can break across spark releases (though this is not the only thing > preventing us from upgrading a running query) > - It is unnecessarily opaque to the user. > I'd propose we require offsets to provide a user readable serialization and > use that instead. JSON is probably a good option. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
