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 Apache Pulsar broker with no Docker and no root.

# The standalone distribution bundles ZooKeeper, BookKeeper and the broker in one process, which
|
|
# is why a single tarball is enough. -nss skips the stream storage (BookKeeper's table service,
|
|
# needed only by stateful Pulsar Functions) and -nfw skips the functions worker; both save
|
|
# several hundred megabytes of heap and a few seconds of startup.

# PULSAR_HOME must point at an unpacked apache-pulsar-<version>-bin directory. Pulsar 4.2
|
|
# supports Java 17 and 21; the transcripts here were produced on Temurin 21.
