> Currently Drill will fail by default to read JSON files with changes in 
> schema, or with several different data types in a list. These files can 
> however be read if the store.json.all_text_mode option is set to true. This 
> option will read all data from the JSON files as varchar and from here the 
> data can be casted to an appropriate type (or filtered out in the case where 
> a cast to numeric is desired but some of the data in the column is a string 
> or boolean type). This is only mentioned on the wiki in this page, but does 
> not really describe all of the use cases of the feature.
