The short version

  • Each has a real cost: CouchDB append-only storage model may have performance implications for certain workloads with high update rates; DuckDB client-server setup remains in beta and not recommended for production distributed scenarios
  • They diverge on capability: CouchDB covers Multi-master Replication, DuckDB covers In-process Execution.

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

DuckDB

  • Client-server setup remains in beta and not recommended for production distributed scenarios
