             Summary: Allow chain ref columns to have multiple chain destinations
                 Key: LENS-711
                 URL: https://issues.apache.org/jira/browse/LENS-711
             Project: Apache Lens
          Issue Type: Improvement
          Components: cube
            Reporter: Amareshwari Sriramadasu
            Assignee: Amareshwari Sriramadasu
             Fix For: 2.3


Right now, we allow ReferenceDimAttribute to be a chain ref column which specifies chain_name, and ref_col from the chain. This improvement proposed is to allow different chain_name, ref_col pair to be accepted.

Usecase :

We have multiple time dimension tables : say HourDim, DayDim and MonthDim.

All of them have timestamp as field which can be mapped to a time field on cube. So, there will be three different chains associated with this reference attribute and optionally the referring column can be different as well.
