--------------------------------
Summary: Improve decimal encoding to use RLE
Key: ORC-49
URL: https://issues.apache.org/jira/browse/ORC-49
Project: Orc
Issue Type: Bug
Reporter: Owen O'Malley
Because decimal was added in Hive 0.11 with no maximum precision, the ORC
encoding for decimal uses arbitrary var ints. Since Hive 0.12, the maximum
precision for decimals fits in 128 bits and thus we can use a much better
encoding using the long rle.
