eespool
Eespool is a term used in computer science to denote a buffering and replay mechanism for event streams and workloads. Conceptually, an eespool provides a durable, ordered repository that absorbs bursts of input data and makes it available to downstream processors at a controlled pace. In practice, it acts as a lightweight spool that decouples producers from consumers, enabling backpressure, fault tolerance, and deterministic replay of past events.
Etymology and history: The word appears to combine 'event' and 'spool', with a nod to traditional data
Design and characteristics: An eespool typically offers append-only storage, partitioning, and a replay index that supports
Uses and examples: In streaming data architectures and event-driven microservices, eespooled data is consumed by processors
Variants and related concepts: Eespool is related to, but distinct from, message queues, commit logs, and log-based
