==========

Implementation of the [Rendezvous or Highest Random Weight (HRW) hashing algorithm](https://en.wikipedia.org/wiki/Rendezvous_hashing) in the Elixir Programming Language ([elixir-lang.org](http://elixir-lang.org))

## Installation

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

```elixir

  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.

```elixir

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:

```elixir

 Rendezvous.get_node object # returns name of elixir node

```
