Hi all, I'm wondering what is the best way to "chain" persistent aggregations in Trident.
Let's say I have a running count of words and I also want to do another aggregation to calculate the total count of all words using the results of the previous aggregation. I can use a persistentAggregate to calculate the running total for each word. However I can't use another persistentAggregate directly chained to that as that would only add the new value instead of decrementing the old value for the group first. What is the best solution to this scenario? Does storm have a way to handle this out of the box? Regards, Can
