interrequest

Interrequest is a term used in computing to describe the relationship and spacing between successive requests issued to a resource, service, or system component. There is no single formal definition, and its meaning varies by domain. In general, interrequest refers to how closely requests are issued in time and how the result of one request may influence subsequent ones.

In web and API performance, interrequest timing affects server load, caching efficiency, and user-perceived latency. Very short interrequest gaps can raise contention and increase tail latency, while longer gaps can reduce throughput. In distributed architectures, interrequest coordination concerns sequencing and state management across multiple calls that implement a higher-level operation.

Design practices that influence interrequest patterns include pacing, rate limiting, backoff, request batching, and queueing. Common metrics include interrequest time (the interval between consecutive calls), throughput, and saturation. Considerations such as clock drift, network jitter, and fairness among clients are important when optimizing interrequest behavior.

Origin and usage: Interrequest is not a standardized term; it appears in engineering discussions and documentation as a descriptive concept rather than a formal protocol. It is related to, but distinct from, interarrival time in queueing theory and from inter-request semantics in specific protocols.
