The short version

  • Each has a real cost: CouchDB append-only storage model may have performance implications for certain workloads with high update rates; TiDB not 100% MySQL-compatible, requiring verification before migration
  • They diverge on capability: CouchDB covers Multi-master Replication, TiDB covers MySQL Compatible.

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

TiDB

  • Not 100% MySQL-compatible, requiring verification before migration

Answered from the vendors’ own pages

TiDB: Is TiDB MySQL-compatible?

Yes, TiDB speaks the MySQL protocol, so existing MySQL clients, ORMs, and drivers work without modification. However, TiDB is not 100% MySQL-compatible.

Source
TiDB: How does TiDB scale?

TiDB provides automatic horizontal scaling with compute and storage scaling independently. It splits compute (TiDB servers) from storage (TiKV) to allow adding nodes without data replication.

Source
TiDB: Does TiDB support analytics workloads?

Yes, TiDB is an HTAP database with TiFlash columnar engine providing analytics capabilities alongside transactional processing on the same data without separate pipelines.
