Component for data processing (moving average, ...)
Hi, in Talend Open Data Studio (or for Open Studio) are there components which already implements data processing like moving average of a specific field in a data flow (which can be added to the flow or replace the original field) or "delta function" which replace a value with the difference between the current value and the previous one and so on?
Or the better way is to implement those functions with a routine able to keep the state (those functions are usually stateful) and using them, for example, in a tMap?
