Kafka, RabbitMQ and Pulsar measured side by side on ordering, replay and consumer scaling by driving the three client libraries directly, plus an operational-footprint measurement of each broker's own distribution. Nine tests, three brokers started without Docker, and every number in the documentation regenerated by scripts/run-all.sh.

# Start a real RabbitMQ broker with no Docker and no root.
|

#
|
|
# RabbitMQ is an Erlang application, so an Erlang runtime and epmd on the path are the whole
|
|
# dependency. Point ERL_ROOT at an Erlang installation and RABBITMQ_HOME at an unpacked
|
|
# rabbitmq-server-generic-unix tarball. Ubuntu 22.04 ships Erlang 24, whose newest compatible
|
|
# broker is 3.10.25; 3.11 and later need Erlang 25.
|
|
#
|
|
# The one non-obvious step is starting epmd yourself: rabbitmq-server's own attempt to start it
|
|
# fails in a container without a resolvable hostname, and the failure surfaces as a forty-line
|
|
# Erlang crash dump ending in {'EXIT',nodistribution}.
