Are there databases that don't require caching?

Question

Database

Hello, I'm still looking for a fast database. And now the question arose - are there any databases with which it is not necessary to use the cache? Well, what I mean is don't use memcached/redis to speed things up. For example, as I know, the database from Mail.Group - Tarantool stores everything in the OP, and at the same time stores information on the disk, but when working with it, all the information is pulled from the OP, I would like to find something in this kind, where for accelerated work with the database it is not required to cache data separately. They advised ElasticSearch, does it store data in OP, or files?

Answer 1

With any database, you can not use caching and the work will be accelerated to hell.
