Deadline propagation

[javiertoja]

The context

I have process that requires a sequence of calls via GRPC, this process involves 3 different systems:

• A
• B
• C

They are connected following the dag: A->B->C, via synchronous blocking calls.

The question

I want to set a tighter deadline in the request between A->B than the time that it might require B to fulfill the request. If the deadline is reached, I would like B to continue processing the request.

This can be achieved if B keeps processing the request even after the deadline. My question relates to the automatic propagation of the deadlines, because I'm wondering if the deadline set in A->B, can be automatically propagated to the request B->C, generating an issue in the process being executed in B cancelling its execution
