# MySQL Patterns
Use this skill when working on MySQL or MariaDB schema design, migrations,
slow-query investigation, queue-style transactions, connection pools, or
production database configuration. Prefer exact version checks before applying a
feature-specific pattern because MySQL and MariaDB have diverged in several SQL
details.
## Activation
- Designing MySQL or MariaDB tables, indexes, and constraints
- Reviewing migrations before they run on large production tables
- Debugging slow queries, lock waits, deadlocks, or connection exhaustion
- Adding keyset pagination, upserts, full-text search, JSON columns, or queues
