Hi Everyone, I am completely new to Pinot and am a little more familiar with Druid. Is it accurate to say that Pinot does not have the concept of pre-aggregations but rather relies on indices to compute aggregates from the raw data instead?

Pinot has ingestion aggregation https://docs.pinot.apache.org/developers/advanced/ingestion-level-aggregations And startree index for pre-aggregation https://docs.pinot.apache.org/basics/indexing/star-tree-index

Thank you @Xiang Fu - I had missed this when reading the docs, this is helpful.

There is also merge roll up background tasks https://docs.pinot.apache.org/operators/operating-pinot/minion-merge-rollup-task#how-this-works

Thanks Mayank, I’ll have a look at this as well!
