L. C. Hsieh created SPARK-34198: ----------------------------------- Summary: Add RocksDB StateStore as external module Key: SPARK-34198 URL: https://issues.apache.org/jira/browse/SPARK-34198 Project: Spark Issue Type: Bug Components: Structured Streaming Affects Versions: 3.2.0 Reporter: L. C. Hsieh
Currently Spark SS only has one built-in StateStore implementation HDFSBackedStateStore. Actually it uses in-memory map to store state rows. As there are more and more streaming applications, some of them requires to use large state in stateful operations such as streaming aggregation and join. Several other major streaming frameworks already use RocksDB for state management. So it is proven to be good choice for large state usage. But Spark SS still lacks of a built-in state store for the requirement. We would like to explore the possibility to add RocksDB-based StateStore into Spark SS. For the concern about adding RocksDB as a direct dependency, our plan is to add this StateStore as an external module first. -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
