>
> Replace HiveDecimal implementation that currently represents the decimal internally as
a BigDecimal with a faster version that does not allocate extra objects
> Replace HiveDecimalWritable implementation with a faster version that has new mutable*
calls (e.g. mutableAdd, mutableEnforcePrecisionScale, etc) and stores the result as a fast
decimal instead of a slow byte array containing a serialized BigInteger.
> Provide faster ways to serialize/deserialize decimals.
