February 2026 monthly summary for apache/kvrocks focusing on replication reliability improvements. Delivered Replication Reliability Enhancements to strengthen WAL replication resilience and efficiency. Implemented socket send timeout, replication lag detection, and exponential backoff for reconnections to prevent WAL exhaustion caused by slow consumers. Primary commit 559a667bef223a07fea350a27168e91fe0a74601 introduces: (1) socket send timeout using poll-based readiness with a configurable timeout (default 30s); (2) replication lag detection at the start of each loop with a configurable max_replication_lag (default 100M sequences); (3) exponential backoff on reconnection (1s, 2s, 4s, … up to 60s) with resets on successful psync/fullsync. New configurations: max-replication-lag and replication-send-timeout-ms. Fixes: related to issues #3356 and #3357. Co-authored-by: hulk <hulk.website@gmail.com>

In 2024-10, delivered a feature in bitnami/charts to expose the metrics port as a NodePort for Envoy, enabling health checks for deployments behind load balancers. This aligns with contour changes to support robust health probes and reduces downtime risk. Commit 1b98ba2878d323a74e28a11540a4a483f6afe450 ([bitnami/contour] Expose NodePort for the metrics port in the Envoy service (#29818)). No major bugs fixed for this repo this month. Impact: improved uptime and reliability for LB-backed deployments; supports smoother auto-scaling and faster issue detection. Technologies/skills: Kubernetes service exposure, Envoy, NodePort, Contour integration, open-source contribution.
