--------------------------------
Summary: Use in-memory derby as the default catalog for unit tests
Key: TAJO-1803
URL: https://issues.apache.org/jira/browse/TAJO-1803
Project: Tajo
Issue Type: Task
Components: Unit Test
Reporter: Jihoon Son
Assignee: Jihoon Son
Fix For: 0.11.0
We are currently using MemStore which is designed to provide the same interface
with AbstractDBStore. This incurs two problems.
* The major problem is that AbstractDBStore is not tested properly by unit
testing. The logic to access catalog is separated into MemStore and
AbstractDBStore, and only MemStore is tested.
* We have to implement both AbstractDBStore and MemStore whenever we modify the
catalog interface even though MemStore is used only in unit testing. This is an
unnecessary burden to developers.
