Rendezvous

Implementation of the Rendezvous or Highest Random Weight (HRW) hashing algorithm in the Elixir Programming Language (elixir-lang.org)

Installation

Add rendezvous as a dependency in your mix.exs file:

  defp deps do
    [
      rendezvous: "~> 0.0.1"
    ]
  end

and run mix deps.get.

Usage

Use Rendezvous.get to obtain for an object the corresponding bucket from a list of buckets. The first parameter defines the hashing algorithm to use.

object = "Some object to put in bucket"
buckets = ["bucket A", "bucket B", "bucket C"]
Rendezvous.get(:sha, object, buckets)

or use Rendezvous.get_node to obtain a nodename from the nodes in an elixir cluster:

 Rendezvous.get_node object # returns name of elixir node
