Stopping a Lambda render

[JonnyBurger]

@jonny Burger Is there any plan (or possibility) to allow a cancel render for renderMediaOnLambda? We have a cancel button when a render is running, but it's just closing a modal while Lambda keeps on going.

hmm, I have to evaluate this to see if it makes sense! in general, once a render function has been spawned, it cannot receive messages from the main function anymore. so we'd have to place a flag somewhere, or maybe with the new lambda streaming functionality we can do something.

We currently don't implement it because when a lambda is invoked with a request, AWS does not give any way to stop the invocation.

so we could do this by putting a flag in the S3 folder and if a lambda recognizes that this file exists, then the render is cancelled.

but we are moving into a different direction now - lambda now supports streaming and larger response payloads, so we are thinking of adopting that and using it instead of pushing + pulling to lambda.

I will consider cancelling a render on lambda for this new streaming model - it should be more natural, since we can for example "cancel" a render by capping the connection.
