We are pleased to announce the immediate availability of RabbitMQ
3.6.0, a new version of the broker that comes packed with lot of
new features. Before
we go on, you can obtain it here:
This release brings many improvements in broker features, development
environment for our contributors, and security. Let’s take a look at
some of the most significant ones.
In order to prevent fast publishers from overflowing the broker with
more messages than it can handle at any particular moment, RabbitMQ
implements an internal mechanism called credit flow that will be
used by the various systems inside RabbitMQ to throttle down
publishers, while allowing the message consumers to catch up. In this
blog post we are going to see how credit flow works, and what we can
do to tune its configuration for an optimal behaviour.
For a while people have looked for ways of implementing delayed
messaging with RabbitMQ. So far the accepted solution was to use a mix
of message TTL and
Dead Letter Exchanges as proposed
by James Carr
a while we have thought to offer an out-of-the-box solution for this,
and these past month we had the time to implement it as a
RabbitMQ Delayed Message Plugin.
