> CDC Scanners like other Global index scanners attempt to remove 
> EmptyColumnOnlyFilter and FirstKeyOnlyFilter from the scan, however it is not 
> enough when EmptyColumnOnlyFilter or FirstKeyOnlyFilter is used with other 
> filters e.g. PageFilter with LIMIT.
> For CDC queries, the user initiated upsert and delete statements do not face 
> any issues as the scan on the uncovered index is only expected to retrieve 
> empty column cell. However, it does not work when we need to retrieve more 
> cells than just empty column e.g. "_CDC_IMG_" column cell should be returned 
> by the delegate scanner for TTL expired CDC events.
> The purpose of this Jira is to remove the filters even when they are used in 
> combination with others.
