> The conditions in the query are mutually exclusive: CUSTOMER.C_NATION in
> ('INDONESIA') and CUSTOMER.C_NATION in ('KENYA'), the result of the
> aggregation query is empty and return "The current query exceeds the data
> range of the model service.Please add a segment."
> *root cause*
> When the query is in the select realization and prune segment steps, all
> segments are returned directly in the case of a full build. However, in the
> case of incrementally build, if the filter conditions are mutually exclusive,
> an empty list will be returned, which will cause the subsequent logic to find
> that the segment is not hit, and set the returned result to be empty. The two
> behave inconsistently.
> *fix design*
> Added property olapContext.storageContext.isFilterCondAlwaysFalse. When
> org.apache.kylin.query.routing.RealizationPruner#pruneSegments judges that
> the filter condition is false, set isFilterCondAlwaysFalse to true. When
> filling sqlResponse, set isFilterCondAlwaysFalse to true and indexType to
> enumeration "Filter Conflict". For the front end, when the indexType is
> "Filter Conflict", no text will be prompted.
