 This is the recommended input option if you want a queue.

-`mdm = MetricDataArray Messagepack-encoded` [MetricDatayArray schema definition](https://github.com/raintank/schema/blob/master/metric.go#L47)  
-This is a kafka input that uses application-level batches stored within single kafka messages.
-It is discouraged because this does not allow proper routing/partitioning of messages and will be removed.
-It only exists to compare performance numbers against kafka-mdm, and make mdm as fast as mdam.
-It also doesn't have the performance tuning options and offset control that has kafka-mdm has. (kafka-mdam always uses latest offset).
