Where each one falls short

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

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

LaunchDarkly

  • Pricing scales rapidly with monthly active users, becoming expensive at scale
  • Limited seats for engineers on standard plans, forcing upgrade to enterprise
  • Advanced features like experimentation and audit logs require higher-tier plans
  • Occasional reliability issues and backend delays reported by users
