Summary: Add function maps between Tajo and RDBMS in JDBC
Tablespace Handler
Key: TAJO-1837
URL: https://issues.apache.org/jira/browse/TAJO-1837
Project: Tajo
Issue Type: Improvement
Components: JDBC STORAGE
Reporter: Hyunsik Choi
JDBC tablespace supports filter push down, including function and various SQL
expressions. But, functions of Tajo is different from those of RDBMS. We need
to two JDBC Tablespace APIs:
* a checking API to check if the expression is acceptable in RDBMS
* a map from Tajo functions to RDBMS functions
