Hi @BowenXiao1999 , thanks for the contribution and always happy to see more databases added to Superset! A few comments:

• would it be possible to add documentation for how to connect to RisingWave here: https://github.com/apache/superset/tree/master/docs/docs/databases ?
• Based on your screenshot, you've selected monthly time grain, but still the table is displaying two values for January 2022 (there should only be one entry for that month). Is time grain working correctly?

Thanks! I will provide more context based on your suggestion.

The reason that these entry is not merged is expected I think, cuz the raw records is chosen and no group by or agg is done on.

After switch to aggregation, they are correctly differetiate.

BTW, we have a demo link: https://risingwave-labs.notion.site/Tutorial-Building-streaming-dashboards-with-Superset-ae1c667aa6734bffa38f0d260734a470, but maybe we should not put it in doc seems it evolve fast.

@villebro PTAL again and feel free to give comments, thanks!

Ah, makes sense 👍 @BowenXiao1999 are you able to add a note to the docs as requested in my previous review? We want to make sure others will also know that RisingWave is also supported!
