> 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
> Assignee: 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.
