Hi Avinash,
  IN the source code the FinalRequestProcessor updates the in memory data 
structures and the SyncRequestProcessor logs to disk.
For deciding when to delete take a look at PurgeTxnLog.java file.

Thanks

Where in the source code can I find this? Also how can I decide when it is
ok for me to delete the logs off disk?

Please advice.

Cheers
