Process Orchestration and Supervision

Different Kinds of Elixir Supervisors

Supervisor

• When your child process list is known ahead of time
• Great when you want to componentize part of your system
  • Encapsulate several processes under one supervision tree

DynamicSupervisor

• When you don't know what child processes will be running under the supervisor
• New processes are started frequently and old processes terminate
  • When paired with the Registry module you can implement a lightweight process backed KV store

PartitionSupervisor (as of Elixir 1.14)

• Horizontally scale (replicate) a supervision tree or processes
• Deterministically route messages to partitions
