What should you do when a WordPress database becomes too large?

First identify which tables use the space. phpMyAdmin and database tools can sort tables by data and index size. WordPress core content may be small while a statistics, security, backup, search, queue, or logging plugin owns most of the database. Table names and plugin documentation usually reveal the source.

Common growth areas include post revisions, expired transients, abandoned plugin tables, form entries, ecommerce sessions, action scheduler logs, and spam comments. Each type has different retention needs. Use the plugin’s cleanup or retention settings when available because direct deletion can break relationships or remove records the application still needs.

Back up the database before cleanup and test on staging. Remove data in manageable batches to avoid long locks and timeouts. Database optimization can reclaim unused space after deletion, but it should be scheduled carefully on a busy site. It does not solve continued growth from an unbounded log or job queue.

Set retention rules and monitor table sizes after the cleanup. Archive records that must be kept for legal or business reasons instead of storing every historical event in the live application. If the legitimate dataset is large, improve queries and indexes, then choose hosting with database resources appropriate for that workload.
