Hi all!
I'm thinking about persisting CDORevisionCache (client side) to disk, to keep it between restarting. Without it, users are often needed to load pretty large models from CDO server upon every restrart of out tool. As it seems to be pretty obvious optimization, but haven't been done yet, I'd like to ask - is there any danger in doing this? As far as I understand CDO, CDORevisionCache only keeps immutable data (CDORevision coordinates (ID, Branch, Version), and revision data (which is immutable as well)), so that should work fine.
Am I wrong?

Hi Leonid,
Long ago André has created a DB-based CDORevisionCache. You may want to study
http://git.eclipse.org/c/cdo/cdo.git/tree/plugins/org.eclipse.emf.cdo.common.db/src/org/eclipse/emf/cdo/common/db/CDOCommonDBUtil.java
..
It hasn't been maintained for quite a while, so it might be broken.
Cheers
/Eike
