Sean Owen reassigned SPARK-25885: --------------------------------- Assignee: Artem Kupchinskiy > HighlyCompressedMapStatus deserialization optimization > ------------------------------------------------------ > > Key: SPARK-25885 > URL: https://issues.apache.org/jira/browse/SPARK-25885 > Project: Spark > Issue Type: Improvement > Components: Spark Core > Affects Versions: 2.2.0 > Reporter: Artem Kupchinskiy > Assignee: Artem Kupchinskiy > Priority: Minor > Fix For: 3.0.0 > > > HighlyCompressedMapStatus uses unnecessary indirection level during > deserialization and construction. It uses ArrayBuffer, as an interim storage, > before the actual map construction. Since both methods could be application > hot spots under certain workloads, it is worth to get rid of that > intermediate level. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
