Azure Durable functions vs Event Hub vs Event Grid to chain functions

Time:09-22

I have several processes represented by azure functions and I need to chain them. They are mainly interacting with the DB and working with the huge amount of data, so each function could take even 1 hour - therefor I can't use HTTP triggers and ADF pipelines (as the timeout is 230s).

What approach would you recommend for such a scenario: To chain couple of long-running functions (3-5 functions).

I have already tried Durable functions. They are working fine, but I had to move all functions inside of one Function app, which I wanted to avoid.

I would like to ask about experiences with Event Hub or Event Grid, if this technology is suitable for such a scenario as well and if yes, what approach would you choose and why? Or any other options?

Thanks a lot for your opinions.

Azure Batch may be a better fit for long-running jobs.

Event Hub should be used as your entry point for Big Data. (when developing IOT solutions, you should use Azure Iot Hub as it's bi-directional).

About Event Grid, it's just a repository for events where you can publish/subscribe to events.

I think you should stay with Durable Functions. As another alternative, you can move the processing part to Azure Container Instances and use Service Bus Queue / Topic to notify the process status.
