Summary: mapWithState Style API Key: SPARK-19067 URL: https://issues.apache.org/jira/browse/SPARK-19067 Project: Spark Issue Type: New Feature Components: Structured Streaming Reporter: Michael Armbrust Priority: Critical Right now the only way to do stateful operations with with Aggregator or UDAF. However, this does not give users control of emission or expiration of state making it hard to implement things like sessionization. We should add a more general construct (probably similar to {{mapWithState}}) to structured streaming. -- 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
