----------------------------------------
Summary: Support ppd when a partition key is casted
Key: HIVE-21477
URL: https://issues.apache.org/jira/browse/HIVE-21477
Project: Hive
Issue Type: Wish
Components: Hive
Reporter: Sébastien BARNOUD
When a query contains a cast on the field belonging to the partition key of a
table, the Predicate Push Down for this field isn't used. In my opinion, as all
field in the partition key are serialized as string, it could be supported.
Example:
Create table demo (value int) partitioned by (uid string);
Create view demo_view as select *, cast(uid as bigint) as id from demo;
select * from demo_view where id = 1;
