What happens to work for other shards, while you cannot target one shard
Test:
- Set up a two shard cluster
- Run a load of N requests per second that hit each shard through one mongos
- Do a thing:
- SIGSTOP one shardsvr
- Trigger an election
- Measure the degradation in throughput and latency for operations that target the other shard. Less than 10% is a decent first target. Ideally there should be 0 degradation.
