--------------------------------------
Summary: Remove uneccessary toSeq when encoding Set to catalyst
Key: SPARK-45849
URL: https://issues.apache.org/jira/browse/SPARK-45849
Project: Spark
Issue Type: Improvement
Components: SQL
Affects Versions: 4.0.0
Reporter: Emil Ejbyfeldt
Currently when encoding Sets to catalyst we first convert them into a Seq.
There is no good reason to do this as the interface we are targeting for
encoding is only `Iterable` which is implemented by Set. So by using Iterable
instead of Seq in some places we should be able to avoid this extra copy when
encoding Sets.
