Election Library

This is a network agnostic implementation of the leader election portion of the RAFT protocol. This library provides no peer discovery mechanism, as such the user of this library must call SetPeers() on the node when the list of peers changes. Users can use any third party service discovery mechanism, such as consul, etc, k8s, or memberlist.

For our internal uses we choose https://github.com/hashicorp/memberlist such that our services have as few external dependencies as possible.

Usage

In order to use the library on the network the user must provide a SendRPC() function at initialization time. This function will be called when RPC communication between election.Node is needed. A node that wishes to receive an RPC call must in turn call Node.ReceiveRPC() when the RPC request is received by what ever network protocol the user implements.

You can see a simple example of this using http by looking at example_test.go
