Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Pebble - as a key/value db
Pebble is the default log storage engine for a multi-raft library named Dragonboat. It was chosen to replace RocksDB and it seems to work well. https://github.com/lni/dragonboat

Is it possible to have more than 1 master available for writes in a raft system?
This is the best open source implementation I've seen that does what you're asking about: https://github.com/lni/dragonboat
memberlist
- library for gossip coordination

Is it possible to have more than 1 master available for writes in a raft system?
I use lightweight https://github.com/hashicorp/memberlist to build initial cluster skeleton (find out what are nodes constituting it)

Leaderless consensus protocol in the wild
Does https://github.com/hashicorp/memberlist count? It’s a gossip-based eventual consistency protocol based on SWIM.

What sort of mature, open-source libraries do you feel Rust should have but currently lacks?
An equivalent of golang's memberlist would be awesome.
-
What's the biggest outage you have ever caused?
I don't know the engineer that did it but I know what happened. There's a library that a bunch of foundational Amazon services use called DFDD. It uses a gossip protocol to handle service discovery and health checking. The open source equivalent is Hashicorp memberlist. To remove a node from the cluster, you have to send a command to an arbitrary node that says a node is dead.

Service discovery library in Rust?
serf uses memberlist which uses the SWIM failure detection protocol (https://www.cs.cornell.edu/projects/Quicksilver/public_pdfs/SWIM.pdf) with the Lifeguard extensions (https://arxiv.org/pdf/1707.00788.pdf).

Ask HN: Which are the best go repositories to read to learn the language?
https://github.com/hashicorp/memberlist
Fairly idiomatic/clean

A Spanner-based distributed locking library
This algorithm assumes you're doing that separately using some sort of membership protocol (e.g. SWIM), and you pass in the membership list that you are keeping up to date with that protocol. If you're curious about those, HashiCorp memberlist and HashiCorp Serf are really good to look at. I believe Consul uses those libraries under the hood.
What are some alternatives?
raft - Golang implementation of the Raft consensus protocol
rust - Official implementation of the IPGen Spec in Rust
doublejump - A revamped Google's jump consistent hash
hashring - Consistent hashing "hashring" implementation in golang (using the same algorithm as libketama)
resgate - A Realtime API Gateway used with NATS to build REST, real time, and RPC APIs, where all your clients are synchronized seamlessly.
spindle - A distributed locking library built on top of Cloud Spanner and TrueTime.
DHT - BitTorrent DHT Protocol && DHT Spider.
LiteDB - LiteDB - A .NET NoSQL Document Store in a single data file
torrent - Full-featured BitTorrent client package and utilities
pjproject - PJSIP project
etcd - Distributed reliable key-value store for the most critical data of a distributed system
futures-rs - Zero-cost asynchronous programming in Rust
