LLMS index: [llms.txt](/llms.txt)

---

This is the parameter navigation page for Pigsty v4.x, without repeating full explanations for each parameter.
For parameter details, please read each module's `param` page.

Cross-checked against the current source and parameter reference pages, the 10 official modules expose **373** public parameters. Native MySQL 8.4 remains a pilot module; its 13 public parameters are listed separately and are not included in the official-module total.

## Recommendations

- Read in this order for first deployment: [`NODE`](/docs/node/param), [`INFRA`](/docs/infra/param), [`PGSQL`](/docs/pgsql/param)
- In production, always review: `*_safeguard`, password credentials, ports, and network exposure
- Validate changes on one cluster first, then roll out globally in batches
