The database alternatives page spans relational, document, key-value, and analytical systems. Begin with the workload and consistency requirement, not a popularity ranking.
- List critical reads and writes, transaction boundaries, and expected growth.
- Load representative data; benchmark p95 latency under concurrent reads and writes.
- Test indexes, schema evolution, backups, restore, and replica failover.
- Verify consistency after a network interruption and how conflicts are resolved.
- Export a sample and measure migration effort for application queries.
Use the simplest engine that meets the requirement with a recovery process the team can operate. A fast isolated benchmark does not establish production suitability.
