❔ Does BlockingCollection TryTake free the consuming thread to do other things?

I'm not too knowledgeable about multi-threading. But I'm trying to use BlockingCollection.TryTake to consume messages like so:

Task.Run(async () =>
{
    while (!_queue.IsCompleted)
    {
        _queue.TryTake(out var command, Timeout.Infinite);
    }
});

Task.Run(async () =>
{
    while (!_queue.IsCompleted)
    {
        _queue.TryTake(out var command, Timeout.Infinite);
    }
});

While _queue.TryTake is waiting for an item - is it occupying the thread such that other API functions will be impacted? My fear is that I have to create n number of these collections. If each one is permanently blocking a thread, then the server will run out of resources. But if the thread is freed to do other things - like process incoming HTTP requests - before being signaled then I should be safe. The documentation is a little confusing, but I'm hopeful that the "blocked thread" is free to do other work:

The thread is then free to do some other useful work before trying again to access the collection.

BlockingCollection Overview

Read about BlockingCollection, a thread-safe collection class in .NET. This class offers features like concurrent adding & taking of items from many threads.

Looks like nothing has happened here. I will mark this as stale and this post will be archived until there is new activity.
