Kubernetes becomes a de facto container orchestration tool, it dominates public cloud providers. However for mission-critical use cases such as distributed RDBMS, there are many caveats that makes poor performance in Kubernetes. In this talk, Shuan Deng will describe the common performance issues when running databases in Kubernetes and how to run distributed RDBMS such as TiDB efficiently in Kubernetes especially in public cloud. The experience is general enough and can be used for other databases too. It covers Linux kernel, cgroups, network and disk configuration tuning.
