use published analyses to test a vendor's claims.
Planned topics
- Jepsen tests databases under partitions and failures and checks histories against models.
- Read: version tested, configuration used, anomalies found, what was fixed.
- Results apply to that version and configuration; verify the current state before relying on them.
- No report is not proof of safety; combine with your own experiment.
