I have a CloudKit-based app running in production, each user may have on average 1000 items in the main entity of the app. I just added an index to one of the entities in my schema, and after deploy, I get the "reindexing production data" progress in CloudKit Dashboard. That thing has been running for days and shows no sign of stopping.
So I tried adding another index to the main entity in the development CloudKit environment, which has just my data (3000 records). Even this is taking a long time and shows no sign of stopping. Do others have this experience?
