How to properly organize the output of tags from the database?

Question

Yii

Hello. I am writing an admin panel in yii2, the question arose of how best to organize the output of meta tags from the database, as well as other information that the client can edit (client mail, contacts). Do I need to cache? Will the site be loaded by constant requests to the database? (For example, for feedback from the database, the client's mail will be requested) Are there any articles on this topic?

Answer 1

Make a conclusion as required by the task.
You need to look at the situation, I don’t think that fast queries will somehow affect the speed of the site.
