--------------------------------
Summary: Support limiting the maximum number of
connections/clients to a zookeeper server.
Key: ZOOKEEPER-2238
URL: https://issues.apache.org/jira/browse/ZOOKEEPER-2238
Project: ZooKeeper
Issue Type: Improvement
Reporter: nijel
Currently zookeeper have the feature of limiting the maximum number of
connection/client per IP or Host (maxClientCnxns).
But to safe guard zookeeper server from DoS attack due to many clients from
different IPs, it is better to have a limit of total number of
connections/clients to a a single member of the ZooKeeper ensemble as well.
So the idea is to introduce a new configuration to limit the maximum number of
total connections/clients.
Please share your thoughts.
