[Hibernate-devel] Cache questions....

[Christian M. <vc...@cl...>]

I am thinking about the cache and i have 2 issues in mind.

Let's imagine as an example a forum application, we got Forum, Thread, =
Message objects.

Forum 1 --> N Thread 1 ----> N Message ( bi directional associations)

First issue:

Forum1 get cached then accessed multiple times from the cache, while =
being accessed, getThreads() method is used.

At the end, we got a graph of objects and since the cache share the same =
reference to the Forum1, it will cache this graph of object, this could =
lead to caching the whole DB over the time...

Second issue:

In a multi threaded environement, multiple threads could get a copy from =
the cache of the Forum1 object, how to deal with the concurrency access =
of non-synchronized collections ?

Comments anyone ?

Best regards
Chris
