-----------------------------
Summary: Custom dimension encoding
Key: KYLIN-1492
URL: https://issues.apache.org/jira/browse/KYLIN-1492
Project: Kylin
Issue Type: Bug
Affects Versions: v1.5.0
Reporter: liyang
Assignee: liyang
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.
