Queries
Find SQL that reads too much data, sorts too much data, or runs too often.
Light database guide
Database optimization is the work of keeping business data fast, safe, and affordable.
For a small shop, this can mean a faster checkout, a booking calendar that loads, inventory reports that finish, and fewer panic upgrades to a larger cloud database plan.
Indexes
Add useful indexes, review composite candidates, and remove waste only after evidence supports it.
Tables
Watch growth, bloat, dead rows, and maintenance signals that affect everyday speed.
Settings
Review memory and maintenance configuration carefully instead of copying tuning snippets.
Cloud limits
Understand whether the problem is query shape, database size, plan limits, or instance scale.
Review process
Use EXPLAIN, staging checks, and rollout plans before production changes.
