history
Project history and usage
fq is a brokered publish-subscribe message queue written around the fqd daemon. The official README describes it as performance-oriented and not designed, at least at the time of that text, for very large numbers of connected clients.
Project history
The GitHub history for the official repository goes back to 2012, and the project later accumulated tagged releases including the 0.10, 0.11, 0.12, and 0.13 series. The current repository is under circonus-labs and is described by GitHub as a fast brokered C message queue that gets out of the way.
The design is built around fqd as broker, exchanges, route programs, queues, and paired TCP client connections. The README documents memory and disk queue types, block/drop policies, public/private queues, persistent or transient queues, HTTP status and submission endpoints, and a SQLite-backed fqd store for peer configuration.
Adoption history
Official documentation lists multiple client surfaces: the C client library, Java client, Node.js package, Go client, and a submission-only HTTP /submit API. This suggests fq was intended for service integration rather than only manual CLI use.
How it is used
Operators run fqd as the broker, configure peers in its SQLite store, and connect clients using queue names, exchange names, route strings, and route programs. The protocol documentation specifies paired command/data TCP sockets, plain auth, bind/unbind/status commands, heartbeat handling, peer mode, and the message frame layout.
Why package nerds care
fq is package-interesting because it is a C broker with many installed tools, a custom binary protocol, optional HTTP superposition, and dependencies such as libuuid, sqlite3, jlog, and optional libbcd. It sits in the same packaging neighborhood as daemons and queue systems where build flags, service files, runtime directories, and client libraries matter.
