I have to say after the 10+ years of struggling with JDBC, Hibernate,
JbdcTemplate
I generally in agree with what Darren has pointed. Within the context of
ACS, declarative transaction support is not as urgent as solving the
problem as we are having in writing queries. Solving basic CRUD and query
problem alone in a consistent pattern can move CloudStack persistence

Hi Lukas, thanks for chiming in.
I do agree that abstracting over NoSQL and SQL is not compelling.
Both have their specific strengths and developers would be foolhardy to
simply assume that swapping one for the other will magically work.

An a non-java developer question: Will that help support different databases ?
like moving to MariaDB ?
On Sat, Nov 23,
MariaDB is a drop in replacement for MySQL, so it can be used with or without
the JOOQ changes.

Jooq does a good job of handling the differences in dialects so as long as you
don't use a feature specific to a database your are fine. More info at
http://www.jooq.org/doc/3.2/manual/sql-building/dsl-context/sql-dialects/
I've used jooq across databases and it's been fine. The sql we use in
Going to an ORM is not as simple as you would expect. First, one can make a
strong argument that ORM is not the right solution, but that can be ignored
right now.
You have to look at the context of ACS and figure out what technology is the
most practical to adopt. ACS does not have ORM

Had a quick look, It looks alright. One question/doubt: will we thigh
ourselves more to mysql if we code sql more directly instead of
abstracting away from it so we can leave db choice to the operator in
the future!?!?

All,
I'm very interested in converting the current DAO framework to an ORM. I
didn't have any experience with java related ORMs, but I've done quite lots
of works with Django and LINQ. So can you add me if this project is started?
Thanks

I've done a lot of analysis on the data access layer, but just haven't had time
to put together a discuss/recommendation. In the end I'd propose we move to
jOOQ. It's an excellent framework that will be very natural to the style of
data access that CloudStack uses and we can slowly migrate to
Hi,
What are the general directions with the persistence system?
What I know about it is:
- It works with JPA (javax.persistence) annotations
- But rather than integrating a general JPA implementation such us
hibernate, eclipselink or OpenJPA it uses its own query generator and DAO
classes to
