Tulip: Schematizing Meta’s data platform

Introduced Tulip, a new binary serialization protocol designed to replace legacy formats like Hive Text Delimited and JSON for data logging and analytics at Meta. Tulip addresses standardization, reliability, efficiency, correctness, and forward/backward compatibility issues by using TCompactProtocol and a robust schema management system. It achieves significant performance gains, using 40-85% fewer bytes and 50-90% fewer CPU cycles for serialization/deserialization compared to previous formats. The system assigns field IDs automatically and ensures indelible field history for complete backward compatibility.
