> Implement HBaseTablespace::getTableVolume() method
> --------------------------------------------------
>
> Key: TAJO-1940
> URL: https://issues.apache.org/jira/browse/TAJO-1940
> Project: Tajo
> Issue Type: Task
> Components: HBase Storage
> Reporter: Jihoon Son
> Assignee: Hyunsik Choi
> Fix For: 0.12.0, 0.11.1
>
>
> Table volume has an important role in query planning. Tajo's query optimizer
> makes many decisions based on table volume, because it is currently the only
> available statistics.
> However, HBaseTablespace doesn't support getTableVolume() method, so our plan
> is not good when the query involves any HBase tables.
