The {{site.data.keyword.mql}} API provides a simple AMQP-based messaging interface for Java™, Node.js, Python, and Ruby. The API is provided for backward compatibility with the earlier {{site.data.keyword.mql}} service. {:shortdesc}
In most cases, {{site.data.keyword.messagehub}} is best used with a Kafka client. The {{site.data.keyword.mql}} API is easier to learn but has very limited scalability and does not offer interoperability with other {{site.data.keyword.messagehub}} APIs.
The {{site.data.keyword.mql}} API is available in the following {{site.data.keyword.Bluemix_short}} regions only: US South, United Kingdom, and Sydney. The {{site.data.keyword.mql}} API not available in the Germany region or in Bluemix Dedicated.
