Term	Kind	Topic	What it is
Primary-Key-Partitioned Upsert Upsert Partitioning Contract, Key-Routed Upsert	pattern	Real-Time Analytical Stores	Routing every version of a record to one partition so a real-time store can resolve the latest value locally - which buys sub-second latest-value queries and fixes the partition count and key budget for the ta…
Real-Time Analytics Store OLAP Serving Layer	tool	Real-Time Analytical Stores	A database built for sub-second aggregate queries over freshly ingested data at high concurrency, serving user-facing analytics rather than internal reporting.
Rollup Policy Pre-Aggregation Policy, Retention Tiering	practice	Real-Time Analytical Stores	The decision - made before ingestion, not after - about what granularity of data is retained for how long, and at what point raw events are collapsed into aggregates.
Sub-Second Aggregation Store	tool	Real-Time Analytical Stores	A database built to ingest continuously and answer aggregate queries over recent data in milliseconds, occupying the gap between OLTP and the warehouse.
Unbundled Event Store Disaggregated Telemetry Store, Object-Storage Column Store	pattern	Real-Time Analytical Stores	A telemetry store that separates writing, compaction and querying into independently scaled services over shared object storage and a metadata store, so retention cost stops being tied to the size of the query…
