---------------------------------
Summary: Limit Hive decimal type maximum precision and scale to 38
Key: HIVE-5565
URL: https://issues.apache.org/jira/browse/HIVE-5565
Project: Hive
Issue Type: Task
Components: Types
Affects Versions: 0.13.0
Reporter: Xuefu Zhang
Assignee: Xuefu Zhang
Fix For: 0.13.0
With HIVE-3976, the maximum precision is set to 65, and maximum scale is to 30.
After discussing with several folks in the community, it's determined that 38
as a maximum for both precision and scale are probably sufficient, in addition
to the potential performance boost that might become possible to some
implementation.
This task is to make such a change. The change is expected to be trivial, but
it may impact many test cases. The reason for a separate JIRA is that patch in
HIVE-3976 is already in a good shape. Rather than destabilizing a bigger patch,
a dedicate patch will facilitates both reviews.
