      Description

      We currently do not install any filters if an offer to a framework times out. We should consider recovering with a filter for some duration.

      This can be interesting in cases where e.g., framework offer processing is backlogged so it cannot accept offers in time. If no filter is installed we could end up allocating to that framework again and again (and exclusively if other frameworks already use more resources than what we offer the backlogged framework at a time).

      If we would instead filter the resources from timed out offers for some allocation cycle, we could extert some form of backpressure on the framework's behalf which could allow it to recover. We also would give a chance that other frameworks can actually use the resources.

      The optimal duration to filter the resources for would depend on the (dynamic) number of frameworks interested in offers and might be hard to determine. Filtering for a single allocation cycle might be a good starting point to get some of the benefits without causing too much new behavior.
