PolarDB-X Zero

Provisions a dedicated PolarDB-X database instance via a single unauthenticated API call. No sign-up or billing is required to start. Instances auto-expire based on the requested TTL (default 7 days, max 30 days). Treat Zero as disposable infrastructure, not an unlimited long-running environment.

PolarDB-X is a MySQL-compatible distributed database supporting distributed transactions, vector search (VECTOR type + vector indexes), full-text search, and horizontal scaling. Use standard MySQL clients/drivers to connect.

Two editions are available:

• Standard Edition: Single-node, 100% MySQL-compatible, supports stored procedures, triggers, vector search. Ideal for most use cases.
• Enterprise Edition: Distributed architecture (CN + DN nodes), supports partitioned tables, GSI (Global Secondary Index), CCI (Clustered Columnar Index). Ideal for distributed SQL testing.

Common Use Cases

• AI agent memory: keep structured state, tool outputs, and retrieval data in one MySQL-compatible backend.
• MCP server storage: provision a disposable SQL database behind MCP tools or custom protocol servers.
• RAG and retrieval demos: combine relational data with vector search and full-text search in one temporary environment.
• Distributed SQL testing: test partitioned tables, GSI, and distributed transactions with Enterprise Edition instances.
• Temporary database workflows: spin up isolated MySQL-compatible sandboxes for tutorials, demos, evals, and short-lived tests.
