> [New] Virtual Fact
> -------------------
>
> Key: LENS-1404
> URL: https://issues.apache.org/jira/browse/LENS-1404
> Project: Apache Lens
> Issue Type: New Feature
> Components: cube
> Reporter: Rajitha R
> Assignee: Rajitha R
> Priority: Major
> Fix For: 2.7
>
>
> Need :
> 1. The current Fact definition does not allow a fact to participate in
> multiple cubes. For scenarios where the same fact needs to be queried in
> different cubes, this would be a limitation.
> 2. Fact definition also doesn’t support filters to be applied on the fact
> data.
> Considering the above two major requirements, a new entity called Virtual
> Fact has been proposed.
> Here is a brief overview about the features of Virtual fact :
> 1. Virtual fact extends a Fact.
> 2. It can belong to a different cube than its parent Fact Cube.
> 3. It can have additional filters which will be used in query rewriting.
