About this episode

The ClickHouse open source project has gained interest in the observability community, thanks to its outstanding performance benchmarks. Now ClickHouse is doubling down on observability with the release of ClickStack, a new open source observability stack that bundles in ClickHouse, OpenTelemetry and  HyperDX frontend.  I invited Mike Shi, the co-founder of HyperDX and co-creator of ClickStack, to tell us all about this new project. Mike is Head of Observability at ClickHouse, and brings prior observability experience with Elasticsearch and more.
