Supervisors

Elixir Supervisors

• restarts child processes when they fail

Strategies

1. :one_for_one

If a child terminates, only that process is restarted.

2. :one_for_all

If a child terminates, all other children are terminated. Then all children (including the terminated one) are restarted.

3. :rest_for_one

If a child terminates, the terminated child and the rest of the children started after it, are terminated and restarted.
