Catalog Service Deployment Incident
A catalog service deployment caused performance issues across the system. Here's how Coroot identified the root cause and provided the fix.
Coroot's Root Cause Analysis
Root Cause: Catalog service deployment (version 0.50) caused performance degradation due to CPU resource contention and database connection issues.
This cascaded to front-end service failures as it depends on catalog for product data. The PostgreSQL database experienced increased query load and CPU contention on node3, leading to connection timeouts and TCP retransmissions.
Coroot's automated analysis immediately identified the catalog service deployment as the root cause
