Summary: This introduces a new binary and library that (microwave: it makes warmup faster..!) that can be used to accelerate cache warmup. The idea is the microwave binary will run cache warmup and capture things that are loaded during cache warmup, and commit those to a file. We can then use that file when starting up a host to get a head start on cache warmup by injecting all those entries into our local cache before actually starting cache warmup. Currently, this only supports filenodes, but that's already a pretty good improvement. Changesets should be easy to add as well. Blobs might require a bit more work.

Mononoke
Mononoke is a next-generation server for the Mercurial source control system, meant to scale up to accepting thousands of commits every hour across millions of files. It is primarily written in the Rust programming language.
Caveat Emptor
Mononoke is still in early stages of development. We are making it available now because we plan to start making references to it from our other open source projects.
The version that we provide on GitHub does not build yet.
This is because the code is exported verbatim from an internal repository at Facebook, and not all of the scaffolding from our internal repository can be easily extracted. The key areas where we need to shore things up are:
- Full support for a standard
cargo build. - Open source replacements for Facebook-internal services (blob store, logging etc).
The current goal is to get Mononoke working on Linux. Other Unix-like OSes may be supported in the future
