RabbitMQ - Performance Tuning

A{rabbit, [{vm_memory_high_watermark, 0.6}]}

B{rabbit, [{disk_free_limit, 0.6}]}

C{rabbit, [{vm_memory_high_watermark, 0.6}, {disk_free_limit, 50000000}]}

D{rabbit, [{vm_memory_high_watermark, 0.6}, {disk_free_limit, infinity}]}

Step-by-Step Solution

Solution:

Step 1: Set memory watermark only
To trigger flow control on memory only, set vm_memory_high_watermark to 0.6.
Step 2: Leave disk limit default
Omitting disk_free_limit keeps it at default, so only memory triggers flow control.
Final Answer:
{rabbit, [{vm_memory_high_watermark, 0.6}]} -> Option A
Quick Check:
Set memory watermark only to 0.6 = D [OK]

Quick Trick: Set only vm_memory_high_watermark to control memory flow [OK]
