Questions tagged [mq]

The term 'mq' refers either to the general topic of message queuing or any of several implementations of messaging middleware with "MQ" in the name. For purposes of Stack Overflow, use the product-specific tags when appropriate. When the question does not refer to a specific product, it is probably better to use the tag [message-queue] or [jms] because of the association of the term 'mq' with specific well-known products.
