go-nsq

The Go package for NSQ. See godoc and the main repo apps directory for examples of clients built using this package. Tests are run via ./test.sh (which requires nsqd and nsqlookupd to be installed). Operationally, NSQ is easy to configure and deploy (all parameters are specified on the command line and compiled binaries have no runtime dependencies). For maximum flexibility, it is agnostic to data format (messages can be JSON, MsgPack, Protocol Buffers, or anything else). Go and Python libraries are available out of the box (as well as many other client libraries), and if you're interested in building your own, there's a protocol spec. It promotes distributed and decentralized topologies without single points of failure, enabling fault tolerance and high availability coupled with a reliable message delivery guarantee.
