---------------------------------------

Thank you for reporting the issue.
We'll look into it.
In the meantime, you can probably just copy the RMQ connector source into your user code and then fix it.

> RabbitMQ connector supports qos, limiting the prefetch to a configurable amout of objects. With the current builder patter that is used by the RMQSource howver, this cannot be configured, leading to an OOM when enough objects are prefetched.
