[roll] Roll fuchsia [fxfs] Instrument LSM Tree Compaction Metrics Add metrics to track the number of compactions, bytes written, and compaction time. These are tracked both on a per-store and global basis. To help identify write amplification issues, this also tracks the maximum layer count, total layers added, and adds exponential histograms for layer sizes and stack depths. Additionally, high-frequency read path metrics (e.g. num_seeks) have been migrated to atomics to reduce lock contention during background compaction.

This repository contains Fuchsia's Global Integration manifest files.
All changes should be made to the internal version of this repository. Our infrastructure automatically updates this version when the internal one changes.
Currently all changes must be made by a Google employee. Non-Google employees wishing to make a change can ask for assistance in one of the communication channels documented at get involved.
First install Jiri.
Next run:
$ jiri init $ jiri import minimal https://fuchsia.googlesource.com/integration $ jiri update
Third party projects should have their own subdirectory in ./third_party.
