It's time to retire the myth that RabbitMQ stores messages in memory. While it was true in the early days of RabbitMQ, and an option for the last 10 years, modern RabbitMQ versions almost always write messages to disk right away. In this blog post we review how different queue types store messages but the short answer is: not in memory!
The Erlang Port Mapper Daemon (epmd) is a built-in component that helps Erlang-based applications (including RabbitMQ) discover each other’s distribution ports.
Together with DNS for hostname resolution, epmd is a piece of infrastructure RabbitMQ nodes rely on for clustering, inter-node communication
and CLI tools connectivity.
While epm is very limited in scope, its exposure to the public Internet often means that Erlang distribution ports are also exposed.
This creates a potential security risk: if attackers find these distribution ports, they'd be one secret value away from being able to run
CLI commands against the node (or cluster).
Recent scans have revealed over 85,000 instances of publicly accessible epmd, with roughly half associated with RabbitMQ servers.
Fortunately, all it usually takes to mitigate this risk is limiting network access to a range of ports. epmd and inter-node communication
can also be limited to local network interfaces, in particular for single node clusters used for running tests.

RabbitMQ 4.1 introduces an exciting new feature: AMQP filter expressions for streams.
This feature enables RabbitMQ to support multiple concurrent clients, each consuming only a specific subset of messages while preserving message order. Additionally, it minimizes network traffic between RabbitMQ and its clients by dispatching only the messages that match the clients' interests.
In this blog post, we’ll explore what AMQP filter expressions are and walk through a simple Java example of how to use them.
This blog post explores use cases of the AMQP 1.0 modified outcome.
This blog post outlines ten advantages of AMQP 1.0 flow control over AMQP 0.9.1, supported by two benchmarks demonstrating significant performance gains. Additionally, we delve into the powerful AMQP 1.0 flow control primitives and how they are used in RabbitMQ.
