> Blink uses an abstract set of data formats to make internal calculations use 
> the binary format as much as possible. This minimizes the serialization 
> overhead and java object overhead.
> It includes:
> BaseRow <=> Row
> BaseMap <=> Java Map
> BaseArray <=> Java array
> BaseString  <=> Java String
> Decimal <=> BigDecimal  //Scale of this object is specified by the user, not 
> automatically determined(like BigDecimal).
> int <=> Date //Flink used to use int in the calculation, but the remaining in 
> Row is still Date, we will change it completely.
> int <=> Time
> long <=> Timestamp
> byte[] <=> byte[]
> BaseGeneric <=> T (GenericRelDataType, we don't know it, let user define 
> serializer)
> primitive type keep same, but use less boxed type.
