Sijie Guo commented on BOOKKEEPER-874:
--------------------------------------
it is non-trivial to do that right now. because bookies don't store LAC out
side of entries. to support this, we might need to ledger storage to store LAC
somewhere.
alternatively, in DL, we do it out side of bookkeeper client, and write entries
to commit previous entries if there isn't traffic.
> Explict LAC from Writer to Bookies

> Current client API piggy-backs LAC with a write. This is keeps reader one
> behind the writer. In order to keep reader up to date with writer even when
> there is a pause in write, proposing the following:
> Writer sends explicit LAC on a configured timeout if there is no write within
> that period.
