> Key: KYLIN-1492
> URL: https://issues.apache.org/jira/browse/KYLIN-1492
> Project: Kylin
> Issue Type: New Feature
> Affects Versions: v1.5.0
> Reporter: liyang
> Assignee: liyang
> Fix For: v1.5.1
>
>
> Currently dimension is encoded by either dictionary or fixed-length. There
> could be better custom encoding to support cases like bank account or card
> ID. This will help enabling some ultra high cardinality columns, and at the
> same time make data more compressed and save some storage.
