---------------------------------
Summary: Apply In-memory database using derby to test cases
Key: TAJO-1648
URL: https://issues.apache.org/jira/browse/TAJO-1648
Project: Tajo
Issue Type: Improvement
Components: catalog
Reporter: Jaehwa Jung
Assignee: Jaehwa Jung
Fix For: 0.11.0, 0.10.2
Currently, Tajo built-in testing cluster start up MemStore. But MemStore isn't
based on database. So if we write complex query for some catalog method,
MemStore would be difficult to adapt the query. So, we need to consider apply
DerbyStore instead of MemStore for the testing cluster. For the reference,
currently DerbyStore provides in-memory database on Derby 10.x version. I think
it would be more useful compare than file based database using derby.
