Supervision Tree

process control

To create fault-tolerant applications, Ergo Framework introduces a process structuring model. The core idea of this model is to divide processes into two types:

• worker

• supervisor

Worker processes perform computations, while supervisors are responsible solely for managing worker processes.

In Ergo Framework, worker processes are actors based on act.Actor. Supervisors, on the other hand, are actors based on act.Supervisor. The role of act.Supervisor is to start child processes and restart them according to the chosen restart strategy. Several restart strategies are available for this purpose. A child process can be not only an actor based on act.Actor but also a supervisor based on act.Supervisor. This allows you to form a hierarchical structure for managing processes. Thanks to this approach, your solution becomes more reliable and fault-tolerant.
