Trino Core

Trino from thesis to production: query anywhere and store nothing, the coordinator/worker split, the connector SPI, the parse-analyze-plan-optimize-schedule-execute lifecycle, the cost-based optimizer fed by connector stats, distributed execution as stages/tasks/splits, dynamic filtering, the asymmetric pushdown contract, the Hive/Iceberg/Delta connectors, federation in practice and its tail-latency cost, resource groups for concurrency, and fault-tolerant execution. Ends with a federated query layer capstone.
