Apache Spark reassigned SPARK-40464: ------------------------------------ Assignee: (was: Apache Spark) > Support automatic data format conversion for shuffle state db > ------------------------------------------------------------- > > Key: SPARK-40464 > URL: https://issues.apache.org/jira/browse/SPARK-40464 > Project: Spark > Issue Type: Improvement > Components: Spark Core, YARN > Affects Versions: 3.4.0 > Reporter: Yang Jie > Priority: Minor > > After SPARK-38888, Spark starts to support use RocksDB as the storage type > of shuffle state db, but when users switch storage types, the original data > store in `LevelDB/RocksDB` will not be automatically converted to another > kind of storage now. The original data store will be retained and the new > type data store will be created when switching storage types. > This is not very friendly for migrating stock users to use RocksDB. If > necessary, consider adding the function of automatic data format conversion: > * LevelDB -> RocksDB > * RocksDB -> LevelDB > > -- This message was sent by Atlassian Jira (v8.20.10#820010) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
