Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

MongoDB

  • 16 MB maximum document size limits large single objects
  • No native JOIN support for relational data operations
  • Higher memory usage due to storing field names with each document
  • Eventual consistency in distributed deployments can cause data stale reads

Oracle Cloud

  • The free trial gives US$300 of credit that expires when consumed or after 30 days, whichever comes first
  • The US$300 cloud credit is available only in select countries
  • Only one Oracle Cloud Free Trial or Always Free account is permitted per person
  • Accounts left idle for 30 days or more are eligible for suspension or termination as abandoned
  • Always Free NoSQL Database is restricted to the Phoenix region
  • Free Tier availability is subject to capacity limits, and the published per-service capacity figures are estimates that assume the entire credit is spent on that one service
