Term	Kind	Topic	What it is
CQRS Command Query Responsibility Segregation	pattern	CQRS	Separating the model that accepts writes from the model that serves reads, so each can be optimised independently — at the cost of the gap between them.
Projection Rebuild Budget Read Model Rebuild Time, Rebuild Service Level Objective	metric	CQRS	The measured wall-clock time to rebuild a read model from scratch, treated as a service level objective, because it bounds how quickly a projection defect can be corrected and therefore whether CQRS is reversi…
Read Model Projection	pattern	CQRS	A denormalised store built and maintained from write-side events specifically to serve one query shape efficiently.
