Re: [rules-users] Snapshot of drools engine's state

IMO that's a very difficult problem to solve.. because if you want to do it every X seconds you can be caught in the middle of an execution. If you delay the snapshot creation for when the execution ends, you will probably caught in the next snapshot creation. Depending on what are you doing within your rules, you can always recreate the session from the scratch. You can also use rules to summarize state and persist that summaries in your external database, that can save you some time.
