Description
The Multiplexer helps the FairCallQueue decide which of its internal sub-queues to read from during a poll() or take(). It controls the penalty of being in a lower queue. Without the mux, the FairCallQueue would have issues with starvation of low-priority requests.
The WeightedRoundRobinMultiplexer is an implementation which uses a weighted round robin approach to muxing the sub-queues. It is configured with an integer list pattern.
For example: 10, 5, 5, 2 means:
- Read queue 0 10 times
- Read queue 1 5 times
- Read queue 2 5 times
- Read queue 3 2 times
- Repeat
