Hi, I’m using Pinot upsert mode for one table and already stored some days’ data. If I change primaryKeyColumns config in schema, such as adding or deleting some filed, do I need to delete and upload this schema and table config to make this change take effect?

@Alice Currently upsert table is able to re-construct the metadata on primary key changes. You may upload the new schema and restart the servers for the table to apply the changes

I wasn't aware of that. Thanks a lot! Deleting my previous comment to not cause any confusion.

Got it. Thanks.
