-------------------------
> Support getting comments from hive table/column for dimensions model view
> -------------------------------------------------------------------------
>
> Key: KYLIN-5872
> URL: https://issues.apache.org/jira/browse/KYLIN-5872
> Project: Kylin
> Issue Type: Improvement
> Components: Modeling
> Affects Versions: 5.0-alpha
> Reporter: pengfei.zhan
> Assignee: pengfei.zhan
> Priority: Major
> Fix For: 5.0.0
>
>
> If it's a normal Hive table, the original column names are fetched, which are
> in English (feature supported).
> If it is a modelview, the dimension name is the original column name by
> default, according to the customer's usage, the customer will not modify the
> dimension name by default, because it is also in English.
> We have discussed with R&D about connecting modelview to get the dimension
> name, on the basis of the dimension name, can we add the original columns
> corresponding to the dimension, which can't be realized due to the jdbc
> specification and the customer scenario doesn't need it. In the end, there
> was no change in this issue.
> Hive table annotations can be synchronized (supported).
> When a modelview, support is required to synchronize column annotations in
> the modelview:
> * dimension, you can synchronize the annotations of the columns
> corresponding to the dimension
> * Metrics, currently synchronize the original columns corresponding to the
> metrics, need to support column annotations
> * CC columns defined as dimensions/metrics, after exposing computable
> columns to BI, annotations can be null (customer wants CC columns to support
> definition descriptions, out of scope of current delivery)
