Hi everyone,
I have a project with two independent glassfish instances. It is not a cluster.
I need a lightweight persistent storage replicated between the two for
some application level authentication data. I would only access them
via JPA.
The data size (few hundred records) and the load (writes hardly ever,
a few reads per minute) are small, so speed or efficinecy are not
issues. Constant overhead and unnecessary complexity are.
(I wouldn't want to fire up a sequoia cluster for this for example, no
matter how much I love it for real databases.)
There already are independent PostgreSQL databases on both sides if
those can be used non-exclusively for this, but I'm hoping there is
some lightweight java database doing just what I need which I haven't
heard of yet. :-)
Any advice appreciated!
