Minimum ReceiverQueueSize value on partitioned topic ?

[jbarotin]

Hi,

I've got a partitioned topic with very low throughput, and then messages stuck.

I want to disable unack messages buffer mechanism, and setting 0 to receiver queue size (as written in documentaton]) is not working, I've got error Receiver queue size needs to be greater than 0 for Topics Consumer.

What the best in this configuration, I tried 1 and message stuck again. Do I have to set it to the number of partition the topic have got ? Or maybee an other parameter is better ? (for example : maxTotalReceiverQueueSizeAcrossPartitions)
