crystal-scatter

Release candidate for v0.1 "John Scott"

Installation

Add this to your application's shard.yml:

dependencies:
  crystal-scatter:
    git: https://git.nekoit.xyz/Archivist/crystal-scatter
    version: ~> 0.1.0-rc2

Usage

require "crystal-scatter"

Create a MetaRing and add services to it, using the weights as a mark of the load the service can handle (example: number of threads each CPU of the servers can handle).

client_ip = "185.124.235.1"

ring = Crystal::Scatter::MetaRing.new(3)

ring.add [
    Crystal::Scatter::Daemon (8 ,    [0,0,0,0,0,0], "https://api01.myservice.com"),
    Crystal::Scatter::Daemon (16,    [0,0,0,0,1,0], "https://api02.myservice.com"),
    Crystal::Scatter::Daemon (12,    [1,0,0,0,0,0], "https://api03.myservice.com"),
    Crystal::Scatter::Daemon (12,    [1,0,0,0,1,0], "https://api04.myservice.com"),
    Crystal::Scatter::Daemon (12,    [2,0,0,0,0,0], "https://api05.myservice.com")
]

ring.get_slices_for(client_ip) 
# => [
#       "https://api01.myservice.com",
#       "https://api03.myservice.com",
#       "https://api05.myservice.com"
#    ]

The output will provide you information to contact the service in a balanced way.
