Lesson 44: Designing the Composite Key
In Lesson 44 of the Uber-Lite Matching Engine series, we design a production-grade RocksDB composite key using the pattern **[H3 Cell ID | Driver ID]** to transform expensive full-table scans into ultra-fast prefix scans. You'll learn how Kafka Streams, RocksDB, H3 geospatial indexing, and partition alignment work together to match riders with nearby drivers in milliseconds. We also cover ghost driver cleanup, dual-write consistency, spatial indexing, partition co-location, and the real-world performance principles used in large-scale ride-matching systems.
