-------------------------------------
Hi [~adoroszlai] ,
My current plan includes:
# Deploying Ozone via Docker Compose and verifying its S3 behavior.
# Starting up `{{{}MiniOzoneCluster`{}}} to verify its behavior.
After that, I'm considering adding some fault injection to see how Ozone
behaves under chaotic conditions. For this, I’m thinking about using
`{{{}MiniChaosOzoneCluster`{}}}, or I might explore other ways to inject faults
later on.
Once I have a more complete plan, I’ll submit a design doc PR for everyone to
review.
> Introduce a linearizability checker to validate Ozone

> Key: HDDS-15561
> URL: https://issues.apache.org/jira/browse/HDDS-15561
> Project: Apache Ozone
> Issue Type: Test
> Reporter: Chung-En Lee
> Assignee: Chung-En Lee
> Priority: Major
>
> To catch subtle consistency regressions like {{HDDS-15052}} without the
> massive engineering overhead of full DST (Deterministic Simulation Testing),
> we propose introducing a post-facto *Linearizability Checker* (e.g.,
> Porcupine, Elle, or Java alternatives).
> By acting as a black-box oracle, the checker will analyze concurrent client
> operation histories generated by our existing {{MiniOzoneChaosCluster or
> docker cluster}} to verify strict correctness with zero core code
> invasiveness.
> Importantly, this checker will also serve as a foundational building block
> for future DST efforts, as any deterministic simulation framework will still
> require such an oracle to validate its execution histories.
