By Robert Hodges
Conference session slides, presented on August 18, 2020 during KubeCon + CloudNativeCon EU Virtual 2020
Presentation recording is coming soon

Databases and stateful apps are gravitating rapidly to Kubernetes, so the sorrows of accidental data loss cannot be far behind. As long-time database engineers and authors of the ClickHouse Kubernetes operator, our team has seen lots of imaginative ways to lose data. We also learned how to prevent them.

The talk starts with standard high availability/disaster recovery models used in DBMS and demonstrates that classic ways to lose data are still alive and well on Kubernetes. We’ll then pivot to Kubernetes-specific disasters-in-waiting, such as the PV that wasn’t, affinity afflictions, and the dreaded fat fingers of fate. The talk will help instill a healthy sense of paranoia and give listeners tools to ensure their experiences with cloud-native data will be happy ones.

Speaker Bios:

Robert Hodges is CEO of Altinity with experience in databases dating back to 1983. ClickHouse is the 20th DBMS he has worked on. His previous database company exited successfully to VMware.
