Drill Community,

Thanks for the quick response to my last question. I am exploring the tool and 
will definitely use it, especially the json capabilities with the flatten 
function. I noticed that Flatten will error on nested maps. I would like to 
exclude these maps to build tables from them later by excluding them since I do 
not know every key in the Json mapping. Is there a way to select * keys from a 
json object except the keys that are maps?

The problem is that I would need to read through millions of records tens to 
hundreds of times per day to achieve productivity with this method. I really 
want to avoid anything manual.

I am looking for something like:

SELECT flatten(filter_not(record[column],array['col1','col2'])) FROM table


All help is greatly appreciated.

Thanks,

Andrew Evans
