Here it is https://issues.apache.org/jira/browse/BOOKKEEPER-896
As soon as possible I will try to write some proposals on the issue Thanks --- Enrico -----Messaggio originale----- Da: Flavio Junqueira [mailto:f...@apache.org] Inviato: venerdì 19 febbraio 2016 00:11 A: dev@bookkeeper.apache.org Oggetto: Re: Bookkeeper and VM-local transport It should be possible to turn off all ZK-related functionality in a bookie, no? The role of the bookie is simply to write ledger fragments and all ZK-related access should be orthogonal to that, and if I'm right, then we could have a flag that disables all ZK accesses. -Flavio > On 18 Feb 2016, at 22:18, Sijie Guo <si...@apache.org> wrote: > > This seems to be a very interesting idea.
