Yes, if you add an ID you can do you processing on one thread with generic attribute names & then join it with your original dataset after this is completed. 

Is that what you meant?

This helps, but the thing is after aggregating with the new names i get aggregated columns as sum_1_2_3 for example, but i want in the output column names as sum_time-12-31-22_time-01-01-00_time-01-01-04 and so on. i mean in the result i also want my original names. but if i do replace the names and do the aggregation then it gives result with new names (obviously). but hot to replace those with original names?
