Subject [discuss] long running actions
Date Thu, 31 May 2018 10:16:24 GMT
Hi all,

taking this discussion from Slack to here:

What would be the best way to support long running actions, especially actions for which the
duration is unknown when the action is started.
An example is e.g. a blackbox container that transcodes a video. The main issue is that OW
limits the amount of time an action can run.

In my mind, one aspect should also be that there must be a way to inspect progress and health
of such a long running action. Maybe using the action logs is a simple way to do this.

Couple of comments that were made on Slack already:
Markus: “it should be possible to make the upper bound of the runtime to be settable to
“Inf”. Would “only” need adjustment in the HttpClient used towards the container to
support an infinite timeout” [1]
Rodric: “callbacks more suitable then” [2]
James: “would think you want some timeout (however large) to stop an action which never
returns.” [3]

Interested in your thoughts.
