   @kishoreg This one will help almost all hybrid use cases with DAYS granularity time column.
   Broker will attach a time filter to both offline and realtime part. If the whole segment is within a day (same time column value), then the filter will match all/nothing, which is fine. If the segment is across two days, and the filter is at the boundary of two days, without this improvement we have to scan the time column (half of the values will match in average); with this improvement we just need to fetch a bitmap.
