Xinrong Meng updated SPARK-38345:
---------------------------------
Description:
Counting elements within an array is a common use case. ARRAY_SIZE ensures the
input to be an array and then returns the size.
Other DBRMS like Snowflake supports that as well:
https://docs.snowflake.com/en/sql-reference/functions/array_size.html.
Implementing that improves compatibility with DBMS and makes migration easier.
