The professional network whose member-facing analytics load produced apache-pinot. Discovered while ingesting pinot-realtime-olap, whose eleven authors are all LinkedIn engineers and whose title — Realtime OLAP for 530 Million Users — is a statement about who the queries come from.
What the source establishes: LinkedIn runs Pinot on 3,000+ hosts across data centres, serving 1,500+ tables and >50,000 queries per second, operated as an internal service with dedicated staff and a deliberately self-service design (schema changes without downtime, indexes added automatically from query-log analysis, table configuration kept in source control).
The company matters to this spoke as an operator, not a vendor: the paper's numbers are production figures from a system LinkedIn runs for itself, which is a different kind of evidence from a vendor benchmark.
