Question

A mallow-bend Function should run only for blobs under /orders, not for every blob in the storage account. How should Event Grid narrow delivery?

Accepted Answer

Add an Event Grid subscription filter on event type and/or subject (for example begins-with /orders). — Specialize the handler with filters. Event type and subject (begins-with, and friends) keep /orders events on this Function and leave the rest alone.

Answer

Use a Service Bus SQL filter on a queue even though the source is Event Grid.

Answer

Delete the system topic and poll every container from a timer.

Answer

Send all blobs to every Function and ignore unused subjects in silence.
