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.

What's everyone working on this week (49/2023)?
Continuing to work hard on a new MetricEngine in GreptimeDB. BTW, If you have a keen interest in Rust or database development, GreptimeDB might be a good starting point. Check it out for some good first issues here.

Practical Tips for Refactoring Release CI using GitHub Actions
Since the very first day of GreptimeDB going open-source, it embraced the automated software building process with GitHub Actions, and leading to the inaugural Release Pipeline.

GreptimeCloud - A Fully Managed Serverless Prometheus Backend
Born from the open-source project GreptimeDB, GreptimeCloud serves as a fully-managed, serverless cloud backend for Prometheus, offering integrated support for remote read/write protocols and PromQL as one of our primary query languages.

Bridging Async and Sync Rust Code - A lesson learned while working with Tokio
Recently, while working on our GreptimeDB project, we encountered an issue with calling asynchronous Rust code in a synchronous context.

A Deep Dive into PromQL — Promql Parser v0.1.0 Written in Rust is Now Available
To explore data stored in GreptimeDB through PromQL, GreptimeDB needs to provide the ability to parse the query into AST (abstract syntax tree), and retrieve data from memory or disk via logical and physical plans. Since there is no ready-to-use PromQL Rust Parser, our team decides to develop it by ourselves. We’re glad to announce that promql-parser v0.1.0 is now available.

Extending Python with Rust
This is truly a fantastic combination -- implement the logic in Rust and use it in Python. GreptimeDB also implements a similar functionality that allows writing Python script to do post-process of SQL query results, with the help of RustPython and Arrow. Maybe this combination can bring a sweet point between performance and efficiency.

Local-first software: You own your data, in spite of the cloud (2019)
Couchdb/pouchdb remains one of the best: it's super easy to setup and is production-ready, but it's gonna be json docs with no transactions, so it can be limiting.
Y.js and automerge emerged as solutions combining CRDTs and content transfer, they look really promising. There is a Y.rs version if that's better for you.
I've always dreamt of building something on top of Syncthing, ie something that would use file synchronization. It's more versatile and will definitely last longer than anything else, and it has some built-in capabilities for having a third party helping transport but not being allowed to read content.
I recently came across https://github.com/superfly/corrosion , a service discovery and state management tool that is working completely p2p. CR-SQLite, in particular, allows multiple tables from multiple databases to be merged thanks to CRDTs. I'm sure there's a lot to build on top of it.
I feel like you're not really interested in full p2p but want some centralization point to manage some auth stuff, so I'd investigate couchdb/pouchdb first.

I'm All-In on Server-Side SQLite
We’re using cr-sqlite as part of our distributed state propagation system. It is indeed easy to bundle in the app!
https://github.com/superfly/corrosion
It would be possible to distribute cr-sqlite changes in many different ways (like you said, http or torrents, etc.) since any change can be applied out of order.
