Hey quick question, when the data is moved to deep storage (after the retention period) is it still queryable or do we need to reload that back like a batch ingestion job?

i think there's a misconception here: deep store is actually used for backup and restore segments e.g. • segments are not being transfer over after retention period, they are uploaded to deep store right after segment generation • other replica segments on different server downloads them from deep store for more info see: https://docs.pinot.apache.org/basics/components/deep-store

Oh so in that case, after retention period, its just removed from the data nodes?

they are not longer queryable once the retention hits

there's several concept of "retention", do you know which config key you are referring to?

Let me read this. Maybe that will clear my doubt. Thanks
