Review Comment:
   This is the whole block. `ServerQueryRequest` will have either `segments` 
(and others) OR `TableRouteInfo` list. If `TableRoutInfo` list is available, 
then logical table objects are created.
   ```
      TableExecutionInfo executionInfo;
       try {
         if (queryRequest.getTableRouteInfos() != null && 
!queryRequest.getTableRouteInfos().isEmpty()) {
           executionInfo = 
LogicalTableExecutionInfo.create(_instanceDataManager, queryRequest, 
queryContext);
         } else {
           executionInfo =
               SingleTableExecutionInfo.create(_instanceDataManager, 
tableNameWithType, queryRequest.getSegmentsToQuery(),
                   queryRequest.getOptionalSegments(), queryContext);
         }
       } catch (NoSuchElementException ne) {
         String errorMessage =
             "Failed to find table: " + ne.getMessage() + " on server: " + 
_instanceDataManager.getInstanceId();
         InstanceResponseBlock instanceResponse = new InstanceResponseBlock();
         instanceResponse.addException(QueryErrorCode.SERVER_TABLE_MISSING, 
errorMessage);
         LOGGER.error("{} while processing requestId: {}", errorMessage, 
requestId);
         return instanceResponse;
       }
   ```
   
   The POC is in https://github.com/apache/pinot/pull/15151
