Without proper management, expired transients accumulate as orphaned rows, causing database bloat and performance issues. The article explains the technical mechanics of transient storage, the lack of automatic garbage collection, and provides an SQL query for manual cleanup. It covers object caching benefits and constraints (including the critical 1MB buffer limit), and outlines best practices like strict namespacing, proper expiration handling, key length management, and the get/check/set pattern for reliable transient usage. ## Full article daily.dev links to this article rather than hosting it.
