------------------------------
Summary: Fixed-length string type support
Key: TAJO-43
URL: https://issues.apache.org/jira/browse/TAJO-43
Project: Tajo
Issue Type: Task
Components: storage
Reporter: Jihoon Son
Currently, Tajo supports only the variable length string (VARCHAR in
databases). This increases the file size and scan overheads.
This issue includes the following sub-tasks.
* Implement a datum class for fixed-length string.
* Add an interface for retrieving lengths of types to the Schema class.
* Add handling codes for fixed-length string to Appender and Scanner classes.
