Major 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)
