Message queuing systems can be used to support a plethora of fundamental services in distributed systems. This paper presents HBaseMQ, the first distributed message queuing system based on bare-bones HBase. HBaseMQ directly inherits HBase's properties such as scalability and fault tolerance, enabling HBase users to rapidly instantiate a message queuing system with no extra program deployment or modification to HBase. As a result, HBaseMQ effectively enhances the data processing capability of an existing HBase installation. HBaseMQ supports reliable and total order message delivery with “at least once” or “at most once” message delivery guarantees with no limit on message size. Furthermore, HBaseMQ provides atomicity, consistency, isolation and durability on any operation over messages.
