Jungtaek Lim commented on SPARK-42592: -------------------------------------- Ideally this should be a part of Spark 3.4.0... Since RC already happened, I'll try to see whether I can add the doc before RC2. > Document SS guide doc for supporting multiple stateful operators (especially > chained aggregations) > -------------------------------------------------------------------------------------------------- > > Key: SPARK-42592 > URL: https://issues.apache.org/jira/browse/SPARK-42592 > Project: Spark > Issue Type: Documentation > Components: Structured Streaming > Affects Versions: 3.5.0 > Reporter: Jungtaek Lim > Priority: Major > > We made a change on the guide doc for SPARK-40925 via SPARK-42105, but from > SPARK-42105 we only removed the section of "limitation of global watermark". > That said, we haven't provided any example of new functionality, especially > that users need to know about the change of SQL function (window) in chained > time window aggregations. > In this ticket, we will add the example of chained time window aggregations, > with introducing new functionality of SQL function. -- 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
