Navis commented on TAJO-1431:
-----------------------------
No, it's for predicate pushdown into storage layer which supports it. Hive
applied this to ORC and PARQUET format and would be simple to port it, too.
HBASE also can use this to apply skip scans, etc (like phoenix).
> Port hive SARG (HIVE-4579) to tajo
