Warning

SingleStore 9.0 gives you the opportunity to preview, evaluate, and provide feedback on new and upcoming features prior to their general availability. In the interim, SingleStore 8.9 is recommended for production workloads, which can later be upgraded to SingleStore 9.0.

sdb-cluster-crd.yaml

This is the custom resource definition for the MemsqlCluster resource. This is the definition of the custom resource that is supplied to the Operator to generate the cluster. This adds the MemsqlCluster resource to the internal api-resources in the cluster so that objects of this kind can be generated.

Create a CustomResourceDefinition file to define the MemsqlCluster resource type.
