Franz

A simple and friendlier persistent message-queue / pub-sub built for speed (blazingly fast)!

The goal of Franz is to be able to handle millions of messages per second with a light memory footprint (it is however, rough on the disk).

Usage

franz --path /path/to/store/data

see franz --help for more details.

Protocol

[message length : u32]([key]=[value] : utf8)

mandatory keys

• version
• topic
• api

example key-values

version=1,topic=test_topic_name,api=produce

Example

spin up a franz instance

franz --path /tmp/franz-test

in another terminal connect to the instance with netcat

echo -ne "\x00\x00\x00\x20version=1,topic=test,api=produce" | nc localhost 8085

send some (newline delimited) messages

hello
world
