Term	Kind	Topic	What it is
Edge Data Consistency	concept	Edge Data Consistency	The consistency model available when data is replicated to many edge locations, where strong consistency would eliminate the latency benefit that motivated the edge.
Read Local Write Global	pattern	Edge Data Consistency	Replicating read-only state to every edge location while directing writes to a single authoritative region, which is the arrangement most edge data stores actually provide.
Variant-Aware Purge Tag-Based Invalidation, Vary-Safe Purge	pattern	Edge Data Consistency	Invalidating every cached representation of a resource rather than one URL - because content negotiation and query parameters create many objects under one address, and a URL purge clears only one of them.
