Question

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!

Do you plan to keep alive these parent processes for a longer time? Does not feel like a best practice design.

Yes Stefan, we need to keep them alive.

OK. I have no idea what your goal is. Long running processes are to be avoided.

Data migration scenarios are a different scenario. Starting a large number of processes with messaging going back and forth puts high load on the system, conduct a load test and keep an eye on health check. Do that outside business hours.

send message and receive message

This is the way to go.

Please consider best practices. For certain use cases like setting up data/data migration this design works well and try to avoid this design for apps.

Thanks Stefan and Shyam, 

Is there any other way to have a communication for an asynchronous sub process and parent process. Please suggest.
