Now, if the GC is going ahead with 'MyId' deletion, will cause inconsistencies.

Yes, Anayway we planned to revisit the GC, considering this approaches once
finalized the approach. I think we should have some timeout here. Within that
time line if node did not rejoins then GC will go ahead clean the data as
replication already might have progressed by that time.

> As per the current design of BookKeeper, if one of the BookKeeper server
> dies, there is no automatic mechanism to identify and recover the under
> replicated ledgers and its corresponding entries. This would lead to losing
> the successfully written entries, which will be a critical problem in
> sensitive systems. This document is trying to describe few proposals to
> overcome these limitations.
