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.

Cloud Scheduler, can there really be only 5000 number of jobs? Is there a limit at how far I can plan tasks into the future? Alternatives?
For example, for a user with the user id of 123-ddd-44232, you would devise a system in your language of choice to hash that ID to the number 2. You then always send the queue messages for that user to queue 2 with the user id in the payload (and not in the URL). This will ensure that FIFO still happens on a per-user basis, but also lets you scale your queues appropriately. Here's an example library in Go that achieves the hashing part with just a few lines of code. These types of libraries are available in most languages.
- Consistent hashing with bounded loads in Golang

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
What are some alternatives?
resgate - A Realtime API Gateway used with NATS to build REST, real time, and RPC APIs, where all your clients are synchronized seamlessly.
raft - Golang implementation of the Raft consensus protocol
emitter-io - High performance, distributed and low latency publish-subscribe platform.
doublejump - A revamped Google's jump consistent hash
ringpop-go - Scalable, fault-tolerant application-layer sharding for Go applications
grpc-go - The Go language implementation of gRPC. HTTP/2 based RPC
DHT - BitTorrent DHT Protocol && DHT Spider.
KrakenD - Ultra performant API Gateway with middlewares. A project hosted at The Linux Foundation
torrent - Full-featured BitTorrent client package and utilities
glow - Glow is an easy-to-use distributed computation system written in Go, similar to Hadoop Map Reduce, Spark, Flink, Storm, etc. I am also working on another similar pure Go system, https://github.com/chrislusf/gleam , which is more flexible and more performant.
etcd - Distributed reliable key-value store for the most critical data of a distributed system
