7 Top-Tier Database Conference Papers Power Core Transaction Speedup of 32% TencentDB TDSQL

SHENZHEN, China,April 24, 2025/PRNewswire/ -- Renmin University and Tencent's joint innovation lab showcased groundbreaking advancements infinancial-grade distributed database systemsat their 2025 annual conference. Over two years,seven paperswere accepted at top database conferences (VLDB, ICDE, SIGMOD), with core technologies integrated into TencentDBTDSQL, achieving32% faster transactionsin state-owned banks and40% improved query speedsin government big data applications.

Key Innovations:

1.Transaction Processing Optimization

  • HDCC Protocol: Combines deterministic (Calvin) and non-deterministic (OCC) concurrency control, resolving cross-mechanism recovery issues. Delivers5.7x performance gains(VLDB 2025).
  • Lion Protocol: Uses LSTM-based workload prediction to optimize replica placement dynamically, avoiding migration bottlenecks. Achieves2.7x higher throughputand76.4% better scalability(ICDE 2024).

2.Storage Optimization

  • HOCO Engine: Enables direct computation on compressed text data via homomorphic compression, offering9.18x higher throughputfor access/modification and7.16x lower latencyfor analytics (SIGMOD 2024).
  • SALI Framework: A scalable learned index that adapts to workload skew and boosts concurrency, delivering2.04x higher insertion throughputunder 64 threads (SIGMOD 2024).

Collaboration Impact: The research bridges academia and industry, with contributions from Renmin University's data engineering experts and Tencent's TDSQL R&D team. Attendees included leaders such asDu Xiaoyong(Renmin) andWang Juhong(Tencent), highlighting the partnership's strategic importance in advancing database technologies for critical sectors like finance and governance.

This collaboration underscoresChina'sgrowing leadership in high-performance database systems, combining cutting-edge AI/ML techniques with robust engineering to solve real-world scalability and efficiency challenges.
