Is there some library or project out there that works like Zookeeper but has no java depende开发者_StackOverflowncy? I'm looking at putting this on an embedded linux system, and need minimal footprint... something like a megabyte or less. I have Lua, C and C++ runtimes, and could put something like NewLISP on there if I had to. Most or all of the clients will be C or C++, a nice command line utility for the benefit of shell scripts would also be useful. http://zookeeper.apache.org/

There is accord,

Accord is a high-performance coordination service like Apache ZooKeeper

It looks like accord is written in c.

Maybe check out etcd:

etcd

A highly-available key value store for shared configuration and service discovery. etcd is inspired by zookeeper and doozer, with a focus on:

• Simple: curl'able user facing API (HTTP+JSON)
• Secure: optional SSL client cert authentication
• Fast: benchmarked 1000s of writes/s per instance
• Reliable: Properly distributed using Raft

Etcd is written in go and uses the raft consensus algorithm to manage a highly availably replicated log.

See go-etcd for a native go client. Or feel free to just use curl, as in the examples below.

There is Doozerd written in Go!
