Yonik Seeley commented on SOLR-7344:

The current implementation is as follows,
- Whenever a request can not processed immediately, it is suspended and placed
on an internal queue.
- We associate a (configurable) timeout value with this request and attach a
callback (using Servlet 3 AsyncListener).
- Whenever the timeout occurs, we attempt to reschedule request. If a thread is
available for the corresponding request type, then the request goes through.
Otherwise we send the HTTP 503 error.

Interesting, thanks for that.
After one request is finished, does something immediately try to pull another
request from the queue? Or do we need to wait for that timeout to hit?
> Allow Jetty thread pool limits while still avoiding distributed deadlock.
