Magma May 2022
Description
Atm magma uses the platform MicroSecond histogram to measure filesystem timings. The MicroSecond histograms have buckets which are powers of two and have issues when values are either too small or too large. To fix this we are moving Magma to hdrhistograms which have dynamic range buckets.
kv_engine moved to hdrHistorgams a while back - MB-22005
