This project causes 16189 implicit searches from macros and I'm trying to find a way to reduce duplicate macro expansions.
Following the idea laid out in this blog post I've created a flamegraph of the implicit search. The computation of ToValue and ToSchema for our basic types is repeated hundreds of time.
For instance, these are the highest offenders of "Implicit search by type":

[info] "scala.reflect.Manifest[test.Event9 :+: shapeless.CNil]" -> 238,
