Previously, we had one “polymorphous” `sample` type in the `storage` package. This commit breaks it up into `fSample`, `hSample`, and `fhSample`, each still implementing the `tsdbutil.Sample` interface. This reduces allocations in `sampleRing.Add` but inflicts the penalty of the interface wrapper, which makes things worse in total. This commit therefore just demonstrates the step taken. The next commit will tackle the interface overhead problem. Signed-off-by: beorn7 <beorn@grafana.com> |
