Implement database schema and data incremental migration for 3.0 release
------------------------------------------------------------------------
Key: IMAP-181
URL: https://issues.apache.org/jira/browse/IMAP-181
Project: JAMES Imap
Issue Type: New Feature
Components: JPA Mailbox
Environment: all
Reporter: Eric Charles
We need a way to upgrade the database (for JPA store) whenever it is needed.
In general, a database upgrade is needed further a JIRA that impacts the
database.
This can be:
1. On a db schema level (table, columns, fk, index,...)
2. On data level (update some data, feed a column with relation keys,...).
Plain SQL would be enough for the first point (not for the second one). PLSQL
(or similar) would be needed for the second point.
To ease things, a java "software" process will developed based on the existing
JPA layer.
The tool should be invoked with JIRA numbers as parameters.
Each provided JIRA number would invoke a DB Change Command.
As POC (Proof of Concept), we will first develop a tool that takes into account.
