Hi all, besides the initiative to allow providing metadata in the Drill metastore, there also can be an option to provide table schema using file and / or table function.
I have created Jira DRILL-6835 [1] with the link to the design document. Those who are interested, are welcome to read it and provide feedback. [1] https://issues.apache.org/jira/browse/DRILL-6835 Kind regards, Arina
