> URL: https://issues.apache.org/jira/browse/HIVE-15335
> Project: Hive
> Issue Type: Bug
> Components: Hive
> Reporter: Matt McCline
> Assignee: Matt McCline
> Priority: Critical
> Attachments: HIVE-15335.01.patch, HIVE-15335.02.patch
>
>
> 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.
