It has no benchmarks so that's not a good sign. But there is another time series database that also allows you to use basic SQL: InfluxDB.

I know about InfluxDB but I was interested in the implementation of the data structure. I'll check the git, thanks

Oh, that's shitty! The git is not the code of Kerf, is some documentation and examples :(
