Important

The SingleStore 9.1 release candidate (RC) is available now. It will be promoted to general availability (GA) soon and at that time it will be renamed to SingleStore 10.

In the interim, SingleStore 9.1 RC can be used to preview, evaluate, and provide feedback on the new and upcoming features in SingleStore 10, while SingleStore 9.0 is recommended for production workloads.

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.
