maxInFlightRequestsPerConnection

maxInFlightReq is a configuration parameter commonly found in network or software systems, particularly those that manage connections or requests. It dictates the maximum number of outstanding requests or connections that can be active simultaneously between two points. This limit is crucial for preventing resource exhaustion, such as overwhelming a server with too many simultaneous requests, which could lead to performance degradation or outright failure.

By setting a `maxInFlightReq` value, a system can effectively throttle the rate at which it sends new requests or accepts new connections. This is a form of flow control, ensuring that the receiving end can process the incoming workload at a sustainable pace. When the number of active requests reaches the `maxInFlightReq` limit, the system will typically pause sending new requests until one or more of the existing ones are completed.

The optimal value for `maxInFlightReq` depends heavily on the specific system, its hardware capabilities, network latency, and the nature of the requests being processed. Too low a value might underutilize available resources, while too high a value could lead to the very problems it's designed to prevent. Tuning this parameter is often an iterative process, balancing performance needs with system stability. It's a fundamental setting for managing concurrency and ensuring reliable operation in distributed or networked environments.
