So this is a perf regression for Scala 2.12 -> 2.13 Root cause of the difference: in Scala 2.13 `toSeq`/`immutable.Seq` defaults to `List`, whereas Scala 2.12's `toSeq` produced a `Vector`. @flipp5b, your proposal looks correct. Do you want to raise a PR to fix it? also cc @LuciferYang, as he did much work on the Scala 2.13 migration. -- This is an automated message from the Apache Git Service.
