Balance Rabbitmq Queue Master Location on queue declaration with min-masters strategy
It may happen that one of the controllers may become unavailable and
Queue Masters will be located on available controllers during queue
declarations. Once a lost controller will be become available masters of
newly declared queues are not placed with priority to such controller
with obviously lower number of queue masters and thus the distribution
may be unbalanced and one of the controllers may become under
significantly higher load in some circumstances of multiple fail-overs.
With rabbit 3.6.0 rabbitmq introduced a new HA feature of Queue masters
distribution - one of the strategies is min-masters, which picks the
node hosting the minimum number of masters.
One of the ways how to turn such min-masters strategy on is by adding
following into configuration file - rabbitmq.config
{rabbit,[ ..
{queue_master_locator, <<"min-masters">>},
.. ]},
