How to maintain relationship between Parent and child processes dynamically

Hi All,

We have a use case where from parent process we will call a webapi and based on the data received the webapi triggers subprocesses dynamically and consider the subprocesses count is pretty high. 

We need the child processes to communicate back the parent process as well


So the key requirement is:

1) maintain the relationship between parent and child processes

2) Have a way to notify parent process at regular intervals - lets say on completion of certain steps in child process

One way to implement this is using a send message and receive message, do we have any other alternative way which doesn't include DB intervention. Please suggest

Appreciate your help. Thanks!
