pengfei.zhan updated KYLIN-5872:
--------------------------------
Description:
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)
> Support getting comments from hive table/column for dimensions model view
