## What it is
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

## Facets
- artifact type: application
- maturity: active
- function: database, vector-database, search-engine
- domain: databases, analytics, large-language-models
- platform: self-hosted, cpp
- tags: mysql-branch, duckdb, hnsw, vector-search, flashback, olap, alibaba, search, linux
