Hi [~ichattopadhyaya] yeah I think this is a good idea to do that. It may not solve the case when a {{dbq1}} already re-ordered to ahead of {{add2}} or {{add3}} in the tlog. But It won't make things worse than today.

> Since updates with different id are independent, therefore it is safe to replay them in parallel. This will significantly reduce recovering time of replicas in high load indexing environment.
