Consistent Volume Group Snapshots: Unraveling the Magic

This conference talk explores the VolumeGroupSnapshots feature in Kubernetes, which addresses the challenge of creating consistent snapshots across multiple volumes for database applications. Learn how this feature, introduced as alpha in Kubernetes 1.27 and progressing toward beta status, solves the critical problem of inconsistencies that occur when snapshots are taken at different times. Discover the internal architecture and key implementation components that work together to achieve write-order consistent snapshots for multiple volumes. Gain practical knowledge on properly implementing this feature in your cloud-native environment and develop troubleshooting skills for potential issues. Presented by Leonardo Cecchi from EDB and Xing Yang from VMware by Broadcom, this 33-minute session provides essential insights for anyone managing database workloads on Kubernetes that require consistent backup solutions.
