July 2025 (2025-07) monthly summary for logicalclocks/rondb-helm: Delivered targeted security and deployment efficiency improvement by implementing conditional certificate issuer creation for TLS-enabled components. The change ensures certificate issuers are created only when TLS is enabled for mysqld, binlogServers, replicaAppliers, and rdrs and when the user has not supplied their own secret. This reduces unnecessary issuer creation, simplifies deployments, and strengthens security posture. The work is captured in commit e4b34688055d3050fe38fdf375b5bbc2502da34d ([HWORKS-2254]).

Month: 2024-11 — Focused on delivering robust, cloud-native RonDB deployments in Kubernetes via the rondb-helm repository. Implemented backup/restore enhancements with S3-compatible storage (including OVH) and improved restore reliability through parallel data restoration, longer default wait times, and tuned startup/health probes to support migrations and upgrades. Introduced deployment-wide configuration improvements for RonDB on Kubernetes: global nodeSelector and tolerations with subchart overrides, upgrade-safe setup jobs (e.g., API key generation for Airflow/OpenSearch) run only on new installations, plus safeguards like configurable initial tablespace size with validation to prevent disk-space overruns. Added optional DiskPageBufferMemory to fine-tune disk-backed buffering. These changes reduce risk during migrations, speed up restores, and increase deployment flexibility and resilience across managed environments.
