Lessons Learned From Etcd the Data Inconsistency Issues

Earlier the year there was an event that shook the cloud native ecosystem. The latest release of etcd had a critical data inconsistency issue. Etcd, the critical component that powers many cloud native solutions including Kubernetes, could corrupt your data. The issue was so bad, that it required every single administrator to take an action or risk their system becoming unrecoverable. This presentation will discuss what led to the data inconsistency issues, how they were discovered, what was needed to fix them and what lessons we learned that could benefit the whole community.
