wsrflite persistence layer (for 6.3 core servers)

[Bernd Schuller]

Hi,

a long-standing issue is that it is quite hard to switch to using
a different database (e.g. MySQL) for the whole UNICORE stack,
since WSRFlite, XNJS, and the service orchestrator use different
persistence implementations.
I'd like to introduce the persistence library used in the XNJS (and the
workflow engine) into wsrflite (and maybe into the service orchestrator)
for the next major release (6.3).

We're starting to see some memory usage issues with HSQLDB, so it would
be good to switch to something that is more easy to control, like H2 or,
for people willing to have some extra admin overhead, MySQL.
I know that at CEA you are working on using MySQL. Would it be a problem
for you if the persistence code in wsrflite would change?

Best regards,
Bernd.

Hi Bernd,

No issue for us if you change the persistence code. It is good news for
us that persistence is going be harmonized between components.

Best regards,
Xavier
