Experience
- Tencent TDSQL, Rhino-Bird Intern, 2026.06 - present
- Project: real-time, high-throughput updates for an OLAP database under limited memory, targeting millisecond-level data freshness
- Completed a real-time update pipeline from TDSQL to OLAP, including transactional change synchronization and end-to-end validation
- Designed a GC-aware in-memory multi-version index to relieve RocksDB version traversal and storage overhead
- Real-time Updates for OLAP Databases, 2024.09 - 2026.05
- Project: real-time, high-throughput updates for an OLAP database under limited memory, targeting millisecond-level data freshness
- Implemented low-memory out-of-place updates and MVCC on columnar data, providing snapshot isolation (SI) for queries
- Achieved high-throughput writes while reducing write-query interference and balancing read/write performance
- Papers: VLDB 2027 (first author), FORMATS’26 @ SIGMOD (second author)
- ~57.9K LoC, pixelsdb/pixels
- Cloud-native Analytic Database with Multiple Service Levels, 2023.12 - 2024.08
- Project: a serverless analytic database on cloud VMs and cloud functions, jointly optimizing performance and cost
- Implemented adaptive multi-SLA query scheduling over a storage-compute disaggregated architecture
- Built a web client and introduced a Text-to-SQL interface
- Paper: ICDE 2025 Demo (student first author)
- ~6K LoC, pixelsdb/pixels-rover
