# JMS Producer The JMS Producer step publishes messages in near-real-time to the Apache ActiveMQ Java Messaging Service (JMS) server or IBM MQ middleware. You may use the JMS Producer step to define a transformation which publishes a [stream of records](/pdia-data-integration/9.3-data-integration/streaming-analytics.md) to a JMS queue for every update of a warehouse. In turn, this queue could then launch another job that flushes an application cache. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
