FerretDB VS tigris

if you have postgres, just use https://github.com/FerretDB/FerretDB

FerretDB is an open source document database that adds MongoDB compatibility to other database backends, such as Postgres and SQLite. By using FerretDB, developers can access familiar MongoDB features and tools using the same syntax and commands for many of their use cases.

There is FerretDB. But they are not fully compatible to Mongo yet.

Feature parity progress with apps:

I presume, that after there is feature parity, then someone could run some benchmarks.

Yep that's serious issue and it's similar to our case. Our main product can work just fine even without SSE 4.2 but MongoDB requires it and then indirectly leads to AVX1 support as we use MongoDB as storage. We did PoC with FerretDB last month and I think it may be good option for Gerylog: https://www.ferretdb.io

Shout out to FerretDB, which is an in progress open source re-implementation of MongoDB atop PostgreSQL.

You can learn more about fly.io and tigris, we will need to create an account on both platforms for this project regardless. Anyway with the theory out of the way let's get started in the next section as we create our accounts and start building the app.

Sounds like you might be interested in the Tigris preview:

Tigris: an open source Serverless NoSQL Database and Search platform

Tigris is an open source serverless NoSQL database and search platform. If you have any questions, or you'd like to contribute to the Tigris open source project.

To try the Tigirs database with express app, visit: https://www.tigrisdata.com/ Signup, and create a test app. It'll provide a command set of npm. Create an express app using it and you'll be able to explore the codebase and queries.

Tigris(https://github.com/tigrisdata/tigris) is one of the supported FerretDB backends and Tigris is backed by FoundationDB, so you can still have the Mongo interface with the reliability and scaling of FDB if that's what you're looking for

Based on the feedback in this thread I have updated the headline on the website to make it about what the product is and moved down the "MongoDB alternative" part. I hope it is more clearer now: https://www.tigrisdata.com/
