Rollup feature

Can we rollup data which is already ingested into druid?
we trying to compress data which older than a year which will help us in using cold historical nodes better.

Suggestions?

Hi Chitra, yes, I think compaction, or “ingest segment”, is what you are looking for: https://druid.apache.org/docs/latest/ingestion/firehose.html#ingestsegmentfirehose
