    • Priority: Critical
    • Resolution: Fixed

      Description

      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.
