Deploy with Kubernetes#
Kubernetes deployments are supported in the following major ecosystems. If you are new to Starburst and just getting started, click the link in the following list for the ecosystem where you are deploying SEP:
Kubernetes cluster design for Starburst Enterprise#
SEP by its nature is built for performance. How it operates differs from other typical applications running in Kubernetes.
Typically, an enterprise application comprises many stateless microservices, each of which can be run on a small instance. SEP’s exceptional performance comes from its powerful query optimization engine, which expects all nodes to be identically sized for query planning. It also depends on each node to have large amounts of memory, to allow parallel processing within a node as well as processing of large amounts of data per node.
By default, once work is divided up among worker nodes, it is not redirected if a node dies, as this can impact performance gains. SEP coordinator and worker nodes are therefore stateful, and clusters by design rely on fewer, larger nodes. However, fault-tolerant execution is available as an optional feature that redirects work to other nodes in order to offer more resiliency for larger batch operations.
Ideally SEP runs within a namespace dedicated to it and it alone. Separate pods can be defined for worker nodes and coordinator nodes in that namespace, and taints and tolerations can be defined for node selection in SEP.
Review the SEP k8s requirements before you begin installing the Helm charts to ensure that you have the correct credentials in place and understand sizing requirements.
