Amareshwari Sriramadasu commented on LENS-59:
---------------------------------------------
This is to allow join chains to be specified for cube. Here is the approach:
* Cube will have set of JoinChain associated
* JoinChain will have name, displayString and description; And the more than
one chain can associated with name.
** Chain is nothing but List of TableReference ( in the order of links)
* Reference dim attribute right nowcan refer to table.column; This will be
extended to include chainName.column. This would allow giving more information
about the reference attribute like display string, description and etc.
So, user can hit the queries directly on chainName.column or the corresponding
reference dim-attribute and join resolver will resolve the chains
> Add metastore changes to store multiple path names
