RabbitMQ Consumer Prefetch value

jigar patel 1 month ago in Server / Execution updated by Wynand Vermaak 1 month ago 1

Hi Team, there is one suggestion to improve RabbitMQ consumer performance. We can divide the load with multiple consumer by specifying prefetch count value. If we are not specifying prefetch value that means single consumer have unlimited buffer means single consumer will pick all the data from queue.

Prefetch meaning "prefetch simply controls how many messages the broker allows to be outstanding at the consumer at a time. When set to 10, this means the broker will send 10 message, wait for the ack, then send the next."

Suggestion : Add prefetch configuration in trigger section of warewolf studio (i.e like trigger concurrency)
