Flavio Junqueira commented on BOOKKEEPER-11:
--------------------------------------------
My understanding of the previous discussions was that it was the overall
preferred option, but I'm happy to consider another option if you see any
problem with Option 3, Dhruba.

> The BookKeeper client currently does not allow a client to read from an open
> ledger. That is, if the creator of a ledger is still writing to it (and the
> ledger is not closed), then an attempt to open the same ledger for reading
> will execute the code to recover the ledger, assuming that the ledger has not
> been correctly closed.
> It seems that there are applications that do require the ability to read from
> a ledger while it is being written to, and the main goal of this jira is to
> discuss possible implementations of this feature.
