Fireworq - Lightweight, high-performance, language-independent job queue system

Fireworq is a lightweight, high-performance job queue system with the following abilities. It is available from ANY programming language which can talk HTTP. It works with a single binary without external dependencies. It is built on top of RDBMS (MySQL), so that jobs won't be lost even if the job queue process dies. You can apply an ordinary replication scheme to the underlying DB for the reliability of the DB itself.

It supports primary/backup nodes. Only one node becomes primary simultaneously and the others become backup nodes. A backup node will automatically be active when the primary node dies. It always works with a single dispatcher per queue which can concurrently dispatch jobs to workers via HTTP. Scalability of workers themselves should be maintained by a load balancer in the ordinary way. This means that adding a worker will never harm performance of grabbing jobs from a queue.
