Subject ActiveMQ replicated leveldb update ordering with zookeeper.
Date Tue, 04 Nov 2014 14:34:58 GMT
Hi,


1. Updates from master to slaves are sequential or parallel ? If sequential
, does master randomly choose a slave each time or is there some order in
which message will go (like master->slave1 and than master->slave2). 

2. How zk communicate with each broker and in what interval ? As mentioned
here http://activemq.apache.org/replicated-leveldb-store.html that the slave
with the latest update gets promoted to become the master.  How does zk
knows which broker has the latest update ? Does zk get notifications from
the slaves for each update ?

Thanks,
Steven
