--------------------------------------

>> This may not be very good for the network too if that entry happens to be 
>> big and also if ensemble + quorum sizes also big.

there is a size limit on bookkeeper entry right now, which is 1MB. the entry 
size couldn't go beyond it.

> 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.
