AliSQL is Alibaba's MySQL branch, forked from official MySQL and used extensively in Alibaba Group's production environment. It includes various performance optimizations, stability improvements, and features tailored for large-scale applications.
- AliSQL Version: 8.0.44 (LTS)
- Based on: MySQL 8.0.44
- DuckDB Storage Engine:AliSQL integrates DuckDB as a native storage engine, allowing users to operate DuckDB with the same experience as MySQL. By leveraging AliSQL for rapid deployment of DuckDB service nodes, users can easily achieve lightweight analytical capabilities.
-
Vector Storage (planned):AliSQL natively supports enterprise-grade vector processing for up to 16,383 dimensions. By integrating a highly optimized HNSW algorithm for high-performance Approximate Nearest Neighbor (ANN) search, AliSQL empowers users to build AI-driven applications—such as semantic search and recommendation systems—seamlessly using standard SQL interfaces.
-
DDL Optimization (planned):AliSQL delivers a faster, safer, and lighter DDL experience through innovations such as enhanced Instant DDL, parallel B+tree construction, a non-blocking lock mechanism, and real-time DDL apply—significantly improving schema change efficiency and virtually eliminating replication lag.
-
RTO Optimization (planned):AliSQL deeply optimizes the end-to-end crash recovery path to accelerate instance startup, shorten RTO, and restore service quickly.
