Summary: After some discussion with Pavel Aslanov, Lukas Piatkowski and Stanislau Hlebik, it was evident that shared future is the best approach for the bookmarks cache. The cache in this implementation maintains a shared future for each repo, fetching the full list of bookmarks. When a list of bookmarks with a given prefix is required, a filter is applied to a full list future. Two locks are used in this implementation: one for adding new repos to the hashtable and one for updating the cache. In both cases the optimistic strategy: "let's first first grab a read lock and try checking if it is good enough" is applied.

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 such as Eden.
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.
