[jira] [Assigned] (SPARK-17829) Stable format for offset log
[ https://issues.apache.org/jira/browse/SPARK-17829?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ] Apache Spark reassigned SPARK-17829: Assignee: Tyson Condie (was: Apache Spark) > Stable format for offset log > > > Key: SPARK-17829 > URL: https://issues.apache.org/jira/browse/SPARK-17829 > Project: Spark > Issue Type: Sub-task > Components: SQL >Reporter: Michael Armbrust >Assignee: Tyson Condie > > Currently we use java serialization for the WAL that stores the offsets > contained in each batch.
