Jepsen finds transaction failures in tested ParticleDB builds

Jepsen found 96 issues while testing ParticleDB builds from 1.1.4 through 1.1.18.11.rc-22, including lost committed writes. Most required only one server and ordinary operations. Many were fixed during testing, but correctness failures remained in the final tested build. Orkes says a later release fixes the remaining issues; Jepsen has not tested that release.

Why it matters

A PostgreSQL-compatible interface does not establish that transactions preserve the guarantees your application needs.

More context

Orkes funded this analysis. Jepsen exercised SQL transactions, process crashes and storage faults; its report includes reproducible examples. Even the strongest transaction mode showed anomalies. Review the exact tested version and workload before applying the findings to a deployment.

Keep in mind

The supplied builds lacked replication, so this was a single-node SQL investigation. The report does not establish the behavior of later builds, distributed replication or vector features.
