Emil Ejbyfeldt updated SPARK-40950: ----------------------------------- Summary: isRemoteAddressMaxedOut performance overhead on scala 2.13 (was: On scala 2.13 isRemoteAddressMaxedOut performance overhead) > isRemoteAddressMaxedOut performance overhead on scala 2.13 > ---------------------------------------------------------- > > Key: SPARK-40950 > URL: https://issues.apache.org/jira/browse/SPARK-40950 > Project: Spark > Issue Type: Improvement > Components: Spark Core > Affects Versions: 3.2.2, 3.3.1 > Reporter: Emil Ejbyfeldt > Priority: Major > > On scala 2.13 the blocks in FetchRequest is sometimes backed by a `List` > while in 2.12 it would be ArrayBuffer. This means that calculating the length > of the blocks which is done in isRemoteAddressMaxedOut and other places now > much more expensive. This is because in 2.13 `Seq` is can no longer be > backed by a mutable collection. -- 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
