I'm using a async/queue function (https://caolan.github.io/async/v3/docs.html#queue) and i'm wonder is there a limit on concurrency parameter?
The function returns a QueueObject, which - according to the documentation - has no limit specified:
Concurrency: an integer for determining how many worker functions should be run in parallel. This property can be changed after a queue is created to alter the concurrency on-the-fly.
Also on the documentation, AsyncFunctions have no limit on concurrency:
An optional integer for determining the maximum number of tasks that can be run in parallel. By default, as many as possible.
