Apache Spark reassigned SPARK-38214: ------------------------------------ Assignee: Apache Spark > No need to filter data when the sliding window length is not redundant > ---------------------------------------------------------------------- > > Key: SPARK-38214 > URL: https://issues.apache.org/jira/browse/SPARK-38214 > Project: Spark > Issue Type: Improvement > Components: Structured Streaming > Affects Versions: 3.2.1 > Reporter: nyingping > Assignee: Apache Spark > Priority: Minor > > At present, the sliding window adopts the form of expand + filter, but in > some cases, filter is not necessary. > Filter is required if the sliding window is irregular. When the window length > is divided by the slide length the result is an integer (I believe this is > also the case for most work scenarios in practice for sliding window), there > is no need to filter, which can save calculation resources and improve > performance. -- This message was sent by Atlassian Jira (v8.20.1#820001) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
