A memcached plugin, for example, would make WordPress store transient values in fast memory instead of in the database. For this reason, transients should be used to store any data that is expected to expire, or which can expire at any time.

Furthermore, what are WordPress transients? Transients are a way of caching data for a set amount of time in WordPress. Unlike storing data in the object cache, transient data is stored only temporarily, with the expectation that it is updated periodically. Transients are always created with a set maximum lifetime, after which they expire and are deleted.
Subsequently, should I delete transients? It can cause performance issues over-time and cause the options database table to group. So ideally you would want to delete expired transients on any of the MainWP Child Sites you manage to improve performance.
Likewise, what is difference between transients and object cache? On a regular WordPress install, the difference between transients and the object cache is that transients are persistent and would write to the options table, while the object cache only persists for the particular page load.The main problem about WordPress transients is that once they expire they are not automatically deleted. They are only deleted when you try to retrieve a transient that has an expired value. So technically, if you create a transient and then never reference again, it will remain in your database forever.
