thanks! it does pretty well when everything is warm but it's pretty bad when things are cold, so it's all about figuring out how to warm the data that you need aggressively. the good news is that for metrics you can simply load all of your desired "fast" into disk and keep it cached and we make it configurable how much time you want to load.

this lets you keep the same performance as something like prometheus without ever worrying about retention or durability, it's just a cost tradeoff of how much you want to keep cached on disk proactively

you can still access cold data, which is good if you want to run a big historical analysis in the background
