Fetching data from the server and maintaining it is a very crucial issue in frontend development. library applications and how we maintain the server state with the library called React-Query. To manage the server state in the frontend and sync with the backend, we need to update, cache, or re-fetch the data efficiently.

A shared characteristic in most (if not all) databases, be them traditional relational databases like Oracle, MySQL, and PostgreSQL or some kind of NoSQL-style database like MongoDB, is the use of a caching mechanism to keep (a copy of) part of the data in memory. So, how do you know if your hot data is in memory? MySQL does.
