Subject [jira] [Comment Edited] (SPARK-17619) To add support for pattern matching in ArrayContains Expression.

--------------------------------------------------------------

It seems really strange to add support for this specific case, when it is doable via UDF.
I'm going to close this as won't fix for now until we hear a stronger argument for it.

On a related topic, I think it'd be useful to have general support for array_exists that takes
in a function as input, but that would require higher order functions in SQL!

> To add support for pattern matching in ArrayContains Expression.
> Array Contains currently only matches the exact value as of now... there should be support
for pattern matching as well. 
> For eg. arrayContains(Seq("\\d*", "\\s*"), "100") returns true.
