------------------------------------

             Summary: Add weights to server side connection throttling
                 Key: ZOOKEEPER-3492
                 URL: https://issues.apache.org/jira/browse/ZOOKEEPER-3492
             Project: ZooKeeper
          Issue Type: Improvement
          Components: server
            Reporter: Jie Huang
             Fix For: 3.6.0


In ZOOKEEPER-3242, we introduced connection throttling to protect the server from being overloaded.
We realize that the costs for creating a local session, creating a global session, and reconnecting
are different. So we associate weights to the costs when throttling. For example, for the
same setting, the throttler will allow more connections to be created if they are local. 
This allows the server resources to be fully utilized.
