Still waiting for someone to open source an observability db that uses distributions as the core storage abstraction instead of just single values.
I thought Circonus’ IronDB was open source but they’ve either brought it back closed source or I was mistaken.
In any case it seems weird that everyone is just rehashing the same space with metrics dbs and not moving to where Google/Circonus have been for a while.
Veneur[1] can compute approximate global percentiles (among other things) during metric collection, and the percentiles can be stored and queried in even in a datastore that doesn't know anything about distributions.
