Sep 1, 2025In Sep 2025, focused on reliability and deployment flexibility for apache/gravitino. Delivered a fix for Kubernetes image resolution (MySQL image repository) to ensure reliable image pulls on Kubernetes 1.28, and enabled deployment configurability by exposing init scripts via values.yaml with helm upgrade support for configmaps (init.sh, gravitio.conf, log4j2.properties). These changes improve deployment consistency across environments, reduce manual steps, and accelerate release cycles.
