  • Operators need verified recovery from object-storage interruption and local chunk removal before relying on archived data.
  • Archive lag and failure signals are required to detect recoverability risk before it affects reads.

PR Summary

Medium Risk
Touches transaction-log catch-up, archiver persistence, and remote chunk reads on the critical data path; mitigated by extensive contract/integration tests and metrics, but production archive behavior still warrants careful rollout.

Overview
Makes archive / cold storage operable with first-class metrics, safer catch-up, and CI gates that exercise S3 and full cluster restore.

Observability: New trogon.eventstore.archive.* instruments (checkpoint lag, pending chunks, retries/failures by operation, remote read duration/outcome). ArchiveMetrics and reader wrappers record archiver backlog and remote reads; lag/pending gauges emit only on archiver nodes. Docs and OTel semconv registry updated; operations guide points operators at these signals instead of noting missing archive metrics.

Runtime behavior: ArchiveCatchup now trims downloaded files to actual size, verifies chunks (including smaller-than-preallocated), cleans temp files on failure, and records retry/failure metrics. Archiver and storage factory pass metrics through; custom S3 endpoints use MinIO blob factory. Archiver option drops “Experimental” label.

Testing & CI: New archive-storage-contract job (RustFS S3, restart-recovery phases, ArchiveIntegration cluster soak). Cluster test harness supports configurable node count, archive options, and a 4-node archiver scenario. Broad xUnit coverage for metrics, catch-up edge cases, lifecycle soak, and S3 contracts behind RunS3Tests.

You've used all free OSS reviews for now. Wait for the free limit to reset to keep reviewing this public repository.

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Walkthrough

The change adds archive metrics, instruments archive reads and retries, validates recovered chunks, and adds S3-backed contract, restart-recovery, lifecycle, and cluster restore tests. Documentation and CI workflows now describe and execute the archive observability and recovery coverage.

Archive metrics contract and wiring
otel/semconv/..., src/EventStore.Core/Services/Archive/ArchiveMetrics.cs, src/EventStore.Core/MetricsBootstrapper.cs, src/EventStore.Core/ClusterVNode.cs, docs/...
Adds archive gauges, counters, and read-duration metrics. Wires metrics into archiver and reader services. Documents the new metrics.
Archive catch-up and storage instrumentation
src/EventStore.Core/Services/Archive/...
Adds retry metrics, configurable retry intervals, recovered chunk validation, temporary-file cleanup, and archive reader stream instrumentation.
Archive processing and metrics tests

Tests retry recovery, corrupt chunks, checkpoint failures, metric values, operation tags, cancellations, and remote read outcomes.
Cluster archive and restart lifecycle
src/EventStore.Core.Tests/Integration/..., src/EventStore.Core.XUnit.Tests/Services/Archive/ArchiveLifecycleSoakTests.cs
Adds configurable cluster sizing and tests archival, cold reads, follower catch-up, restart recovery, and local chunk materialization.
S3 contract and restart recovery gate
src/EventStore.Core.XUnit.Tests/Services/Archive/Storage/..., .github/workflows/common.yml
Adds isolated S3 bucket setup, RustFS contract execution, staged outage and restart recovery tests, and archive restore integration coverage.

Estimated code review effort: 4 (Complex) | ~60 minutes

Merge Risk: 🟠 High · up to ec513

The PR is not merge-ready because archive recovery may stop instead of retrying after a storage interruption, while CI and workflow changes can cause flaky or unexpectedly failing checks and expose credentials. Failure metrics may also under-report archive read problems.

Poem

A rabbit counted chunks by glow,
And metrics made the tallies show.
RustFS slept, then woke once more,
With cleanly restored archive lore.
Hop, hop — the checkpoints held their line,
And S3 shone through the retry time.

Report a clear failure when the archive checkpoint does not advance.

If the archive checkpoint stalls, Task.Delay(100, timeout.Token) throws TaskCanceledException after three minutes with no indication of the expected and observed checkpoint values. That makes CI failures of this gate hard to diagnose.

Move the shared S3 settings to job-level env.

The four EVENTSTORE_S3_TEST_* values and the recovery bucket name repeat in every step. Define the shared values once under jobs.archive-storage-contract.env and keep only EVENTSTORE_S3_RECOVERY_PHASE per step. That removes the risk of the values drifting between steps.

The unavailability assertion can pass for the wrong reason.

Assert.ThrowsAnyAsync<Exception> accepts any exception. A misconfigured endpoint, wrong credentials, or a missing bucket satisfies this test even when the storage is available. The elapsed-time assertion also compares against 10 seconds while the token expires after 5 seconds, so it only detects a token that the client ignores.

Assert on the expected failure shape, for example an HttpRequestException, AmazonServiceException with a connection error, or OperationCanceledException, and exclude authentication and validation errors.

Assert on the cancellation base type, and remove the dependency on zero-delay cancellation.

This test uses the default retryInterval of TimeSpan.Zero. GetArchiveCheckpoint therefore awaits Task.Delay(TimeSpan.Zero, ct) with an already-canceled token, and the test depends on that call throwing. If the delay completes instead of observing cancellation, the retry loop never exits and this test hangs.

Set an explicit non-zero retryInterval, and assert on OperationCanceledException as the sibling tests do. Assert.ThrowsAsync<T> requires an exact type match, so the current assertion also breaks if the runtime surfaces a plain OperationCanceledException.

The checkpoint assertion is not synchronized with the metric write.

WaitFor returns when archive.NumCheckpoints reaches 1. The fake increments that counter inside SetCheckpoint. ArchiverService calls _metrics.SetCheckpoint(_checkpoint) only after SetCheckpoint returns, so metrics.Checkpoint can still hold the value written by LoadArchiveCheckpoint when the assertion runs. The 200 ms delay inside WaitFor hides the gap most of the time, but the test can fail intermittently in CI.

Poll the metric instead.

25-61: 🗄️ Data Integrity & Integration | 🔵 Trivial | ⚡ Quick win

Consider excluding ChunkDeletedException from the failure counter.

ChunkDeletedException is an expected outcome while the archive is scavenged. ArchiveCatchup treats it as a retryable, benign condition, and S3Reader raises it for any missing key. Here it increments TrogonEventstoreArchiveFailureCount in the same way as a real remote error.

Operators who alert on the failure counter will see benign spikes during scavenge. Record the read outcome, but classify a deleted chunk separately from an I/O or authorization failure.

♻️ Proposed change for the full-chunk path
 		catch (OperationCanceledException)
 		{
 			throw;
 		}
+		catch (ChunkDeletedException)

authentication, endpoint, and bucket-validation failures. Keep the bounded
timing check aligned with the five-second CancellationTokenSource timeout.

In `@src/EventStore.Core/Services/Archive/Storage/ArchiveStorageReaderMetrics.cs`:
- Around line 25-61: Update both GetChunk overloads to catch
ChunkDeletedException separately from genuine failures: record the read outcome
using the appropriate ArchiveOperation without incrementing the failure counter,
then rethrow it; retain RecordFailedRead for other non-cancellation exceptions
and preserve existing cancellation behavior. Update the missing-chunk assertion
in S3Tests to expect the revised failure measurement.
