Flavio Junqueira commented on BOOKKEEPER-272:
---------------------------------------------
Hi Rakesh, One clarification. In the design document of BOOKKEEPER-237, we say:
_Auditor would be forming the recovery chain based on the myIds added to the
ZooKeeper under the zNode /ledgers/bookie/myId_. If the chain is logical and
formed through zookeeper, then I don't understand why the auditor needs to be
involved in the chain formation. In my understanding of the proposal, the role
of the auditor is essentially to assign work (replication) to bookies. What am
I missing?
> Introduce chain of bookies for distributing the re-replication

> The idea is to form logical chain and each Bookie will be taking care each
> other. On any Bookie failure, his neighbour will act and initiate
> re-replication.
> For example:
> Assume we have 1,2,3,4,5,6 bookies and will be forming the following chain
> 01 <- 02 <- 03 <- 04 <- 05 <- 06 <- 01
> Here, each one should take care of my immediate predecessor node. The lowest
> node should always care the highest node and is forming the logical closed
> chain.
