Todd Lipcon commented on KUDU-721:
----------------------------------
Thanks [~wesmckinn]. I definitely think that a fixed 16-byte size is overkill
for a lot of the use cases of DECIMAL. Even just 4 bytes is enough to store
monetary amounts up to $40M which is probably significant for your average
e-commerce application, etc, so I'd hate to waste 12 bytes on the wire or in
memory for such schemas.

> [~mgrund] identified that without DECIMAL type, we're going to have issues
> with a lot of the tests tables that Impala uses. Also, since we're targeting
> some financial applications, it seems pretty crucial. This JIRA is to track
> the work necessary to support it.
