Apache Pinot

General question: is there any way to handle deduplication in Pinot like InfluxDB does <https://docs.influxdata.com/influxdb/v2.6/write-data/best-practices/duplicate-points/|here>. Basically, I want to specify some columns in a table which need dedup. If there are multiple rows which have same values for those columns, Pinot will only keep 1 row even though the other columns have different values. Is there any way to do that in Pinot? Thanks.

Realtime. That doc has what we need. Thanks.

If I add `primaryKeyColumns` to an existing schema, will it take effect? Or do I need to recreate the schema to make `primaryKeyColumns` work?

Or do I need to reload all segments? Will that work?

You need to rebootstrap as this will be a backward incompatible change
