Tried with streamsets Windowing Aggregator but couldn't get the results. can anyone please suggest effective way to perform this.

Hi, You can develop a custom processor and save the accumulated value. It's better to save your calculation result outside of StreamSets to minimize the chance of data loss on failure. Khanh
