If you're new to timeseries databases, you may be confused about what ASOF joins are, and how useful they are.

Timeseries data has volume built-in because it’s cumulative. You don’t want a single picture: you want the whole movie!

The logic behind that was obvious: we were very strong in this area; thus we should bring the battle to where we are strong!

In future posts, we will dig more into the specifics of benchmarks and design choices. ## The Penrose stairs of performance If you are following database innovation you can see that nearly every database vendor out there has at least one benchmark putting them in the first place. With every vendor selling the fastest database there is, you end up in a [Penrose stairs](https://en.wikipedia.org/wiki/Penrose_stairs) situation where everyone is faster than everyone.
