[CDO] Configure release conditions for cached objects [message #1867803]

By default, there is some garbage collection for objects in the session cache. Is it possible to configure the behavior somehow?

In my case, I want to keep the server as responsive as possible, even if this takes up more memory. So keeping everything in memory would be an option (but I also need to have persistence).

Before you activate your repository you can call repository.setRevisionManager(). The revision manager should be configured with a custom CDORevisionCache, The cache must extend the right base class, the one that is used without your customization (double-check the repository mode you're using, branchin g, auditing, or non-auditing). In your custom cache override createReference() to create strong references or override cleanReference() to change the eviction policy.

Thanks for the answer. That approach does indeed work. But in our case, the memory usage turned out to be too high. We are now keeping regular java references to the required objects so that they are not cleared from the cache.
