The another main reason developers use redis is, it stores data in memory (RAM) not in disk. So it is faster to read data from memory (RAM) after L1, L2, & L3.

Yes it is true developers need to avoid re-computing data every time using complex queries. But they could've used database only to store that computed data instead of redis, right.

Answer is right but not direct if its complex queries we will store another table, the diff is cache will store in L1, L2 level the performance is very fast to compare DB, and this is expensive
