Rollup vs Transform

I have a use case where I have a nested aggregation query, now I want to ingest the data for all the aggregation results into a new index. I was going through the Elasticsearch documents and found out that Aggregation does not support nested aggregation. Will rollup help for for both historical and new data?

Hi @ajitesh,
Could you expound upon your use case, because elastic does support nested aggregations.
