The short version

  • Only CouchDB has a free tier, so it costs nothing to try first.
  • Each has a real cost: Amazon RDS no super-user access or direct host connectivity limits advanced customization; CouchDB append-only storage model may have performance implications for certain workloads with high update rates
  • They diverge on capability: Amazon RDS covers Multiple DB Engines, CouchDB covers Multi-master Replication.

Where each one falls short

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

Amazon RDS

  • No super-user access or direct host connectivity limits advanced customization
  • Pricing unpredictable and expensive compared to GCP alternatives with equivalent features
  • Limited access to system procedures and tables requiring advanced permissions
  • No Oracle RAC (Real Application Clusters) support for high-availability Oracle deployments

CouchDB

  • Append-only storage model may have performance implications for certain workloads with high update rates
  • Requires network synchronisation for cluster data consistency; can introduce latency in multi-master scenarios
  • No explicit support for complex joins; MapReduce queries may be inefficient compared to relational databases
