ASF GitHub Bot reassigned SPARK-45511: -------------------------------------- Assignee: Apache Spark > SPIP: State Data Source - Reader > -------------------------------- > > Key: SPARK-45511 > URL: https://issues.apache.org/jira/browse/SPARK-45511 > Project: Spark > Issue Type: New Feature > Components: Structured Streaming > Affects Versions: 4.0.0 > Reporter: Jungtaek Lim > Assignee: Apache Spark > Priority: Major > Labels: SPIP, pull-request-available > > State Store has been a black box from the introduction of the stateful > operator. It has been the “internal” data to the streaming query, and Spark > does not expose the data outside of the streaming query. There is no > feature/tool for users to read and modify the content of state stores. > Specific to the ability to read the state, the lack of feature brings up > various limitations like following: > * Users are unable to see the content in the state store, leading to > inability to debug. > * Users have to perform some indirect approach on verifying the content of > the state store in unit tests. The only option they can take is relying on > the output of the query. > Given that, we propose to introduce a feature which enables users to read the > state from the outside of the streaming query. > SPIP: > [https://docs.google.com/document/d/1_iVf_CIu2RZd3yWWF6KoRNlBiz5NbSIK0yThqG0EvPY/edit?usp=sharing] > > -- 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
