AliSQL is Alibaba Cloud's open-source MySQL branch based on MySQL 8.0.44, adding a DuckDB columnar analytical storage engine and native HNSW vector indexes. It retains full MySQL client protocol compatibility while adding features like Native Flashback and binlog durability optimizations.

Use cases

• run analytical OLAP queries on MySQL data with DuckDB columnar engine
• store and search vector embeddings with HNSW indexes in MySQL
• query historical table data with AS OF TIMESTAMP flashback
• reduce commit I/O for large transactions with binlog optimizations
• migrate existing MySQL apps to a database with vector search support

When to choose

• you need MySQL compatibility plus analytical query acceleration
• you want vector similarity search without adding a separate vector database
• you need point-in-time flashback queries on InnoDB data

When to avoid

• you need a fully upstream-supported vanilla MySQL with vendor support
• you require non-GPL licensing for your product
• you depend on MySQL features or plugins not present in this branch
