In this sub-session, the assistant established a functional test cluster and monitoring UI for the Filecoin Gateway's distributed S3 storage system. Initial work included building a comprehensive cluster monitoring dashboard with real-time polling and React components, plus a Docker Compose-based test infrastructure with two Kuri nodes, shared YugabyteDB, and supporting scripts. Several operational bugs were fixed: permission suppression for YugabyteDB file permissions, idempotent database initialization, corrected container status checking, and CAR staging configuration. The pivotal correction came when the user identified a fundamental architecture flaw—the assistant had been running Kuri nodes as direct S3 endpoints, violating the roadmap's requirement for separate stateless frontend proxy nodes. This led to a complete redesign: generating per-node independent settings files, restructuring docker-compose into a proper three-layer hierarchy (S3 proxy on port 8078 → Kuri nodes → YugabyteDB), and implementing the routing layer as specified in the roadmap, completing Phase 3 of the implementation plan.
Segments
- The assistant built and iteratively debugged a test cluster for the horizontally scalable S3 architecture, ultimately correcting a major architectural error to properly separate stateless S3 frontend proxies from Kuri storage nodes with independent configurations.Distributed S3 architecture, Test cluster debugging, Stateless proxy design, Docker Compose orchestration, Real-time monitoring dashboard, Configuration management
- Built and debugged the S3 frontend proxy binary, segregated per-node database keyspaces, and staged 14 logical commits to complete the three-layer horizontally scalable S3 architecture.Database keyspace segregation, Dual CQL connections, S3 frontend proxy binary, Test cluster debugging, Per-node isolation, 14 logical git commits, Health checks & metadata
- The assistant debugged and fixed the test cluster's web UI and S3 proxy by resolving HTTP route conflicts and missing CQL columns, then implemented live cluster monitoring with real-time metrics collection, upgraded the cluster topology RPC to include health checks, added I/O throughput and latency charts to the React frontend, renamed SLA to SLO with a 350ms threshold, and verified that both Kuri storage nodes and S3 proxies now display operational statistics.Debugging container infrastructure issues, Implementing real-time cluster monitoring, Enhancing frontend UX with role distinction, Verifying live metric capture and display, Renaming SLA to SLO with threshold fix, Automating Docker/React build pipeline
