Queue: Reference handler instead of creating it

[jiw-mh]

Right now every queue requires a separate lambda function to be deployed, causing in a lot of lambda functions and consequently provisionedConcurrency. Wouldn't it be possible to specify a string as worker which references a function defined in the functions section of the Serverless specification?

It depends on how you define the queue and how you handle the jobs. If you use Lift, you can't, you'd have to define the handler manually.

Also I'm curious why use separate queues if you don't need separate handlers?

Would it be unthinkable to change that?

Using the eventSourceARN it is possible to route the events internally to handle the queue items with different logic, so eventually they will result in different actions, just as they would if there was a different lambda for each event.

Right, so indeed that wouldn't work at all with Lift. I think there's an interesting problem behind this (I'm still not sure this architecture is the right approach, but full context would be needed), but I'm afraid I wouldn't have time right now to dive into it I'm sorry.
