Suresh Marru commented on AIRAVATA-14:
--------------------------------------

Raman, are you working in this? Its assigned to you. Since this jira removed mysql dependency, we may still want to resolve this even though the focus is on using JCR bases registries.

> Based on the following discussion we agreed to remove mysql dependency and move to Apache Derby.

> I agree with Patanachai and Simon's observations. But I see good support for Derby integration. I am fully supportive with an assumption that it will bring down the initial configuration steps. I want to focus on other aspects of Airavata but will add JIRA tasks for the components which will need Derby integration. Soliciting volunteers in advance to close them.
