The MQ Light messaging API is based on AMQP 1.0. The API provides most of the messaging capability needed for the majority of publish/subscribe and point-to-point messaging flows.

The MQ Light API has the following messaging features:

  • At-most-once message delivery
  • At-least-once message delivery
  • Topic string destination addressing
  • Message and destination durability
  • Shared destinations to allow multiple subscribers to share workload
  • Client takeover for easy resolution of hung clients
  • Configurable read ahead of messages
  • Configurable acknowledgment of messages

Some of the benefits of AMQP are as follows:

  • An open standardized protocol
  • Compatibility with other open source AMQP 1.0 clients
  • Many open source client implementations available


The IBM MQ Light API is based on the OASIS Standard AMQP Version 1.0 wire protocol. **
