For some more advanced/demanding use cases, advanced server parameters are key to provide the performance/latency or security that applications will require, either due to contractual or complaince obligations.

FlowControl throttles writes for consistency sake, but for very low latency use cases it becomes a factor for "perceived" client SLO breach. In such particular scenarios, the cost consistent across all replicas is higher than low latency reply.

redactClientLogData is important to ensure complaince with several sectors such has identity management.

TTL monitor should be able to be controled via API call to better manage the migrations between self-managed clusters and Atlas.
