WordPress Transients works like a basic built-in cache system used by WordPress core and theme. Transients API is used by theme developers, it offers a simple and standardized way of storing cached data in database temporarily by giving it a custom name and a time-frame after which it will expire and be deleted.
Earlier we have discussed about deleting old transients in WordPress to reduce database size and optimize it.
Likewise clearing transients options before a backup saves space in your backup files whereas deleting them on a live WordPress site optimizes your database, makes your website fast and utilize less resources.
When deleting transients on your WordPress website, you not loose anything important as that system is build to rebuild the cache of transient options after a specified period of time, if they do not exist.
