Where can I download the example datasets?

[Zzzz-zz]

I want to download the example datasets of nebula graph in the offical website. But I only find the datasets of "Game of Throne" in the online demo demostration. If you can provide the download link of other demos' datasets will help me a lot. Hope you can update the document in the offical site where you can provide the datasets' download link.

Hi, after cloning the code, try execute make up in the nebula/tests folder, the database would be started automatically with example datasets loaded into the database, such as the 'nba' dataset.

When starting up the database, the scripts will pick a random port for the graphd service and show it in the standard screen output like this:

Start nebula successfully

Then, you could coonect to this graphd via this port: 17885. The default user and password are root and 'nebula'. Ignore those failed messages reporting socket errors, it's just the script keeps trying to connect while the service is still starting.

Thanks a lot ～ But I want to find the datasets in ".CSV" format. According your description, I need to build a nebula server in my mac and excute the testing case. After that, exports the dataset in specific format?

[xtcyclist]

In the nebula/tests/data/nba folder, there are the *.csv files for the 'nba' dataset, for example.

nebula-importer is needed to load those *.csv files. Please note that the configuration yamls in the above folder are for automatic loading only (because they are using an old format).

If you want to load the data yourself, please refer to this config: https://github.com/vesoft-inc/nebula/pull/4404/files. (I previously run into the same problem that I want to load the data manually, so I wrote this config. But I found out the make up can do what I need for me.)

And, you can find nebula-importer here: https://github.com/vesoft-inc/nebula-importer.

For basketballplayer dataset, you could execute:
:play basketballplayer in nebula-console

Besides a `.ngql file could be find in docs docs.nebula-graph.com.cn

Also, I created several datasets:

• https://github.com/wey-gu/nebula-shareholding-example
• https://github.com/wey-gu/covid-track-graph-datagen
• https://github.com/wey-gu/fraud-detection-datagen

It is difficult for other people's data sets to fully meet their own scenarios. You can try to create a test data set that is suitable for your own business scenario. There is a tool for generating graph data: https://github.com/golfxiao/graph-datagen.
