Hi, I recently started learning about using Apache Drill and I've been trying to figure out something for a while now, but I can't seem to find any resources that document what I'm trying to do. Essentially, I'm trying to query the data types for each column that I have within a Parquet file using drill. I've scanned over the documentation on the Drill website, but nothing I have tried has worked.
I will admit that I'm not in any means a Database administrator, so this is somewhat out of my knowledge realm. I'm a web developer that is integrating drill querying within my applications. So for instance, I have a parquet file that has the following columns: name | address | age | occupation | timestamp I would like to be able to query that parquet file and find out what each column type is in the following manner: | field | type | |------------|--------| | name | string | | address | string | | age | int | | occupation | string | | timestamp | date | If you can point me in the right direction or potentially give me an example of how I would write a query to output the above, I would really appreciate it. Thank you for your time. Best regards, -- Max Orelus +1 (202) 361-9946 [email protected]
