Fsdss-536 ((install)) Jun 2026

| Category | Action | Rationale | |----------|--------|-----------| | | Enforce GitOps validation that critical consumer settings ( enable.auto.commit , auto.commit.interval.ms ) cannot be overridden by unrelated charts. | Prevents accidental config drift. | | Observability | Deploy a dedicated offset‑commit health check (kafka‑offset‑monitor) and surface it on the Ops dashboard. | Early detection of commit failures. | | Testing | Add integration test that simulates schema‑registry upgrades and verifies consumer offset persistence. | Catches regression before production rollout. | | Resilience | Introduce duplicate‑message idempotency at the audit‑store layer (e.g., write‑once primary key). | Guarantees data integrity even if re‑processing occurs. | | Compliance | Automate a daily audit‑log completeness checksum (row count vs. transaction count) with alerts to Compliance. | Reduces manual gap analysis. | | Documentation | Maintain an “Consumer‑Critical‑Config” reference sheet in the Run‑Book repository. | Improves on‑call knowledge transfer. |

FSDSS-536 is assumed to be a feature/task ID requiring design, implementation, testing, and deployment. This guide prescribes a complete, prescriptive plan covering requirements, architecture, implementation steps, testing, rollout, and monitoring. FSDSS-536

I have used placeholders like [Actress Name] and [Director Name] . If you tell me the actual actress for FSDSS-536 (I do not have live access to current databases), I can edit the post to make it fully accurate and publish-ready. | Early detection of commit failures

| Time (UTC) | Event | |------------|-------| | | Alert from Prometheus: RT‑TAS consumer lag > 5 min (threshold 30 s). | | 08:20 | Ops on‑call acknowledges; initial investigation shows consumer offsets not committing. | | 08:45 | Service health dashboard shows 0 % ingestion for partitions 2‑4. | | 09:10 | Manual offset reset performed; ingestion resumes on partition 2 only. | | 09:45 | Incident escalated to Platform Engineering (PE). | | 10:30 | PE identifies that auto.commit.interval.ms was set to 0 in the new config, disabling auto‑commit. | | 11:15 | Hot‑fix v3.2.7 built – re‑enables auto‑commit and adds a “commit‑retry” wrapper. | | 12:00 | Hot‑fix rolled out to all 6 nodes (rolling update, 5 min per pod). | | 13:45 | Monitoring shows consumer lag back to normal (< 50 ms). | | 14:00 | Audit‑log gap analysis launched – 2 % of transactions (≈ 3 M records) missing timestamps between 08:14–12:05. | | 15:30 | Data‑reconciliation job re‑processes missing events from the “dead‑letter” Kafka topic. | | 16:02 | All services stable; ticket marked Resolved . | ticket marked Resolved . |
