Matt McCline created HIVE-15335: ----------------------------------- Summary: Fast Decimal Key: HIVE-15335 URL: https://issues.apache.org/jira/browse/HIVE-15335 Project: Hive Issue Type: Bug Components: Hive Reporter: Matt McCline Assignee: Matt McCline Priority: Critical
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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
