Hey all! I'm exploring datahub as a possible project to take on in my new role, and was wondering what data access datahub gets when it's connected to a database? I didn't see this mentioned in the documentation anywhere. Is there no issue because it's hosted locally on your docker image? Thanks for what may be a silly question! Sorry if this a silly question! If you could point me in the right direction that'd be super helpful!

Hi @best-yacht-69562! There’s a bit of variability between databases, but generally speaking DataHub is extracting metadata from: • System tables (ie.

information_schema

, catalogs, etc.) to determine what datasets are available • Query logs - what queries have been executed & by whom - this informs our lineage graph & overall usage stats • Datasets themselves for high-level data profiling I encourage you to check out our docs for the specific database you’re interested in - you should be able to find detail on what level of access is required & for what purpose https://datahubproject.io/integrations/

Omg the integration page had it all 🙈
