-------------------------------------------------------
Resolution: Implemented
Fix Version/s: NIGHTLY
Committed the patch. Did some small fixes addressing some typos. Thanks Buddhima for Contribution. One thing i note is if a message comes to the message store with a smaller sequence number than current processed out message it will be dropped. As a future improvement we can add a feature where users can configure an optional sequence to handle this messages.
