> Project: Tajo
> Issue Type: Improvement
> Components: Storage
> Reporter: Hyunsik Choi

> Fix For: 0.12.0, 0.11.1

>
> {{Tablespace::getVolume}} plays a role to guess or compute exactly the table
> volume. This volume result is usually used for join optimization. But,
> currently {{Tablespace::getVolume}} just returns whole table volume. It may
> cause sub optimal join order, especially in partitioned tables or indexable
> tables like HBase.
> The main objective of this patch is to improve {{getVolume}} method to take
> filter predicates and return more reasonable volume sizes according to
> predicates.
