Description

Currently DocumentStore performs various background operations like

1. Cache consistency check
2. Pushing the lastRev updates
3. Synchrnizing the root node version

We should capture some stats like time taken in various task and expose them over JMX to determine if those background operations are performing well or not. For example its important that all tasks performed in background task should be completed under 1 sec (default polling interval). If the time taken increases then it would be cause of concern
