> Due to the difference in the storage format of decimal data type in parquet versus the
in-memory format within Drill using the decimal data type is not performant. Also some of
the rules for calculating the scale and precision need to be changed. These two concerns will
be addressed post 1.0.0 release and to prevent users from running into this we are disabling
decimal data type by default.
