Streaming queues in IBM MQ 9.2.3
By now, you have probably seen the announcement for IBM MQ 9.2.3. The first thing to mention is that Nastel had support for 9.2.3 right away. We work with the IBM teams to ensure we are ready for any new releases and changes. This newsletter won’t go into details of all the enhancements included but will focus on one, in particular, streaming queue. As a quick summary, a streaming queue allows you to define an alternate queue to which every message sent to the original is duplicated.
The image below is just a simple example of the basic concept. There are 2 queues: MyQueue and CopyQueue. As messages are put to MyQueue, MQ Automatically makes a copy in CopyQueue. So in the example, messages A and B are put to MyQueue by the application. As each message is put, the queue manager automatically makes a copy in the CopyQueue. As the messages are read by the receiving application, the copied messages remain. You can select whether the put is required or optional (such as if CopyQueue gets full). The current limit is 1 stream queue per primary queue although the streaming queue could be a topic.
There are many different use cases for streaming queues. For example, if you wanted to create an audit trail for all activity through the queue. Another case would to be create an alternate workflow for the messages.
However, the use case that is very attractive from our perspective is the ability to access the data flowing through the queues. This might bring to mind Application Activity Events which are commonly used with Nastel XRay to track messages. Activity events are good for tracking activity and can be used to get payload and are a good option in many cases. They are best for tracking the application calls and when messages were put and received. With streaming queues, you get the raw data directly from the source, not a reformatted message to process. Since messages contain the business information, you can now answer questions like “how many orders today were greater than 1 million dollars?" Well, you can if you have a way to collect this data. Nastel XRay is specifically suited for this as well. By listening to your data, you can get various data and related insights without having to make any application changes.
This ability has existed when topics are used including in IBM MQ and Kafka, but for traditional MQ applications that use queues, this creates a new avenue to get insight.
