jamie-vesoft··on Show HN: Nebula – a distributed graph database written in C++
There is a Getting Started series in the GitHub wiki page: https://github.com/vesoft-inc/nebula/blob/master/docs/manual...

Check out the Getting started YouTube video here if you prefer video tutorials: https://www.youtube.com/channel/UC73V8q795eSEMxDX4Pvdwmw

Also some FAQs: https://github.com/vesoft-inc/nebula/blob/master/docs/manual...

If you are interested in the architectural design of the project, here are some articles for your reference:

Overview: https://github.com/vesoft-inc/nebula/blob/master/docs/manual...

Storage engine: https://github.com/vesoft-inc/nebula/blob/master/docs/manual...

geospatial is also available in Nebula Graph.:)

As to the storage system, Nebula Graph is based on multi-group raft and RocksDB.

As far as I know, Common Clause can be attached to any open-source projects. The main purpose is to prevent cloud providers monetizing from the project without contributing back. So Nebula Graph's main license is Apache 2.0, meaning that to most users it is open source, no different than any other open source projects. :)

Currently the project has been deployed in multiple leading internet companies in China, including Tencent, MeiTuan (Chinese Yelp), Red (Chinese Pinterest), Vivo, and so on.

Glad you loved the query language!

The C++ client is PR ready now:

Geospatial support has already been merged to the code base. :)

Glad you loved the query language. Simplicity and versatility are our design goals for the language.

Thanks for showing interests in Nebula Graph!

In some production deployments, the graph size reaches hundreds of billions of edges and data size reaches dozens of TB.

Glad you liked the project! Hosting service would be the main monetization method. In addition, we will be providing consulting, training and all sorts of enterprise services.

Exciting! I know Graphistry from Twitter.

Thanks for your interest! :)

Good question re data loading! Currently there are two tools for this purpose: 1) Spark Writer which enables you to load data from DWH to Nebula Graph via Spark: https://github.com/vesoft-inc/nebula/blob/master/docs/manual... 2) CSV importer if you don't have to import very large data from RDBMS to Nebula Graph: https://github.com/vesoft-inc/nebula-importer

The visual will be released by the end of this week. :)

That's exactly what Common Clause is pursuing IMO.
