You forget RethinkDB, it's a shame
I've been poking around, testing and breaking database servers for a long time (more than 20 years today). But a few years ago I came across a jewel, the grail, one of the best solutions available. Under the radar, shunned for whatever reason, RethinkDB is nonetheless one of the finest database server projects I've ever tested.

Ask HN: Anyone Using RethinkDB in Production?
RethinkDB[0] looks like a "too good to be true" type of database. Anyone using it in production? What is your experience like? What are the pros and cons?

Help wanted for a project idea - A multi-room live chat experience, similar to Twitch chat's functionality
Since you’re not new to the field you might want to peek https://rethinkdb.com/ since it got picked up as an open source project.

What's the big deal about key-value databases like FoundationDB ands RocksDB?
No I don't think that's relevant. They implement their own btree it seems [0].
They don't use a key-value store library.
I know it's a bit of a fine line. But I'm talking about standalone libraries people embed across different applications/databases. That's what RocksDB/LevelDB/Pebble are.

Python, the usefulness of "dataclass"
A Data Objects represents data which can be saved inside a database. This concept is in the heart of SQLAlchemy, but as the name should be obvious: it's for SQL Database (in general). Today, there are now document databases too (like MongoDB, ArangoDB, RethinkDB that I love so much, or even PostgreSQL). So, a "data" is like a "structured and typed document" that you save "as is". That's not the same paradigm, not the same controls. There are advantages and disadvantages, but we won't debate that here.

Tools/kit/api/framework for creating a Synchronous app?
There are multiple ways to share data between two (or more) instances of your app: - you can use a shared storage, such as Cloud Firestore, - you can build your own backend (based on a real-time database, such as RethinkDB), - or you can rely on local communication using the Multipeer framework you linked.

Codebases to read
I'm partial to how cleanly written https://github.com/google/leveldb is. It is a reasonable size to fully read & grok in not too long.
