Matt McCline commented on HIVE-11468:
-------------------------------------
Patch 2 adds more tests and verifies integers, strings, and doubles (probably
never will be used) will vectorize in Vectorized Struct IN(). No decimal,
timestamp, date for now.
Note the semantic type checking for struct constants is extremely inflexible.
Types must be exact, so you'll see capital L being added in the struct
expressions to make integers type bigint, or the query will not parse...
