Hi all, this is my first project and we are looking at

ingestion aggregation

feature. I know it is a new feature. I read the doc and example https://docs.pinot.apache.org/developers/advanced/ingestion-level-aggregations but it is hard to find examples from other places. In the example, I dont see any primary keys in the schema, then how can Pinot know which fields to group by?

The implicit key here is all dimension + time column values, they all have to match for metrics to be aggregated. cc: @Johan Adami
