Is it possible to extract metadata information from data about a data source?
eg:- Let’s say I have a mysql source configured in dremio and want all tables and relations in a schema so that one can do another level of data modeling and use dremio as a data Fabric layer?
Have a look here and see if this is what you’re looking for: http://docs.dremio.com/advanced-administration/querying-metadata.html
@kelly That helps. One quick question though. Does dremio anywhere extracts source relations. FK/PK constraints?
Currently we do not extract relationships, but that is something Dremio learns from user queries and can suggest to users as they interact with datasets.
And then there are all those sources without relationships, like mongo and elastic.
