Hello! I think of implementing a distributed queue and distributed map using ZooKeeper.
I need to store somewhat like 50-100K of nodes being processed in a cluster on ZooKeepers. Most operations would be - check if node exists - create node if it does not exist - update node data (atomically) - rename node from one subtree to another one - concurrently queried/updated by 5 processes and 10 threads each, so 50-100 clients connected, estimated 100-500 requests per second. I am concerned about network traffic in the cluster and memory usage on each node (since it will hold entire replica of data). Please advice if ZooKeeper is a correct library for that. Thanks! -- Eugene N Dzhurinsky
