- WordPress maintenance and troubleshooting
Database maintenance protects integrity, recoverability and predictable performance.
It should be based on measured growth and known ownership rather than routine deletion of unfamiliar tables or options.
Back Up Before Database Work
Create a current database export before:
- Bulk updates.
- Search and replace.
- table repair.
- schema changes.
- migration.
- cleanup.
- plugin removal with data deletion.
Verify that the export can be imported.
Monitor Growth
Review:
- Largest tables.
- Rate of growth.
- revisions.
- sessions.
- logs.
- queues.
- transients.
- metadata.
- ecommerce records.
- search indexes.
Growth can be legitimate. Identify the feature and retention requirement.
Integrity and Repair
Database errors can result from server failure, storage problems or damaged tables.
WordPress supports a repair mode through WP_ALLOW_REPAIR, and WP-CLI can invoke database repair utilities. Remove public repair access immediately after use.
Contact the hosting provider when the database service or storage layer is failing.
Query and Index Review
Slow queries need profiling evidence.
Index changes affect reads, writes and storage and should be tested on a copy of representative data.
Maintenance Windows
Operations that lock large tables or rewrite many rows can affect visitors and background jobs.
Schedule, monitor and define rollback.
Frequently Asked Questions
Does WordPress need regular manual database optimization?
Not on a universal schedule. Monitor actual growth, health and query behavior.
Can I repair a database without a backup?
A repair operation can change data. Create a recoverable backup first whenever possible.
