Subject S4 Load Balancing Mechanism
Date Thu, 11 Oct 2012 03:52:01 GMT
Hi All,

I want to figure out the mechanism of load balancing in S4.
In the paper and web site, it says ZooKeeper takes this responsibility, but
the description is not very clear.
I want to figure out that how ZooKeeper does load balancing.
For example, if there are two working PE nodes, and 120 messages per
second. The adapter distributes these messages evenly, 60 per PE node,
right?
When one PE node is added into the cluster, does it mean ZooKeeper balances
the messages, 40 per PE node?
And how does ZooKeeper decide which message to be distributed to which
node?

Thanks.
Yu
