--------------------------------
Summary: 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
Fix For: 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.
