Redis is not faster than your SQL database, it's just different.

It's usually under less load. It's key-value, not relational, so looking up simple things can feel faster (but would sometimes also be fast if you just used a hash index on your SQL database).

It's not magical performance dust, just different.

Also it doesn't (usually) have a ton of indexes to update on each write.

@nateberkopec @jasonrclark it's not faster, it just can do less, so you do less with it.

Which makes it (feel) faster at the things it does.

@nateberkopec I get your point, but do you have numbers or is that a hot take? 🤔
