Jacky Li updated CARBONDATA-1419:
---------------------------------
Description:
Add a new encoding for Double data type:
1. AdaptiveFloatingCodec, it will multiple the column value by Math.pow(10,
decimalCount) and do type cast from double to target data type like byte,
short, int
was:
Add two new encoding for Double data type:
1. AdaptiveFloatingCodec, it will multiple the column value by Math.pow(10,
decimalCount) and do type cast from double to target data type like byte,
short, int
2. AdaptiveDeltaFloatingCodec, it will first calculate the delta of column
value and maximum value and multiple by Math.pow(10, decimalCount) and do type
cast from double to target data type like byte, short, int
