Workers duration limit confusion
Use event.waitUntil() to delay cancellation for another 30 seconds or until the promise passed to waitUntil() completes.The docs on Duration Limit (https://developers.cloudflare.com/workers/platform/limits/#duration) says that using
waitUntil() delays Worker expiration untils 30 secs *or * the promise completes. The "or" is confusing me. Does that mean it'll continue for the longer of the two (and potentially indefinitely while awaiting the Promise)?1 Reply
30s max
The explaination here is perhaps a bit better: https://developers.cloudflare.com/workers/platform/limits/#how-long-can-a-subrequest-take
When the client disconnects, all tasks associated with that client’s request are proactively canceled. If the Worker passed a promise to event.waitUntil(), cancellation will be delayed until the promise has completed or until an additional 30 seconds have elapsed, whichever happens first.
