> Time Spent: 2.5h
> Remaining Estimate: 0h

> Currently before doing a bootstrap dump, we abort all open transactions after
> waiting for a configured time. We are proposing to abort only write
> transactions for the db under replication and leave the read and repl created
> transactions as is.
> This doc attached talks about it in detail
