Andries Engelbrecht commented on DRILL-2848:
--------------------------------------------

It is feasible to enable decimal by default in future versions?

A number of BI and Analytical Software tools that work with Drill requested 
this.

> 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.
