A fast Message-Queue base on zookeeper.
Jafka mq is a distributed publish-subscribe messaging system cloning from Apache Kafka.
So it has following features:
(1)Persistent messaging with O(1) disk structures that provide constant time performance even with many TB of stored messages.
(2)High-throughput: even with very modest hardware single broker can support hundreds of thousands of messages per second.
(3)Explicit support for partitioning messages over broker servers and distributing consumption over a cluster of consumer machines while maintaining per-partition ordering semantics.
(4)Simple message format for many language clients.
