I have a requirement, i can keep only few days data like last 7 days in my ES cluster.
but i want to store the summary data fro long time.
like number of count for any query in every 5 minutes . so later on i can compare with any time data
This is a need that we see sometimes. Unfortunately we don't have a go-to solution for it right now. So you would have to do it on client-side and store aggregated information about the indices that you are removing somewhere.
