--------------------------------
Summary: Replace filter and contains with intersect
Key: SPARK-36580
URL: https://issues.apache.org/jira/browse/SPARK-36580
Project: Spark
Issue Type: Improvement
Components: Spark Core
Affects Versions: 3.3.0
Reporter: Yang Jie
filter on Set can use intersect instead
*before*
{code:java}
val set = Set(1, 2)
val others = Set(2, 3)
set.filter(others.contains(_))
{code}
*after*
{code:java}
val set = Set(1, 2)
val others = Set(2, 3)
set.intersect(others)
{code}
Semantic consistency, but it looks simpler
