Cassandra¶

Cassandra is the Schema for the cassandras API.

Required

apiVersion (string). Value aiven.io/v1alpha1.
kind (string). Value Cassandra.
metadata (object). Data that identifies the object, including a name string and optional namespace.
spec (object). CassandraSpec defines the desired state of Cassandra. See below for nested schema.

connInfoSecretTargetDisabled (boolean, Immutable). When true, the secret containing connection information will not be created, defaults to false. This field cannot be changed after resource creation.
disk_space (string, Format: ^[1-9][0-9]*(GiB|G)*). The disk space of the service, possible values depend on the service type, the cloud provider and the project. Reducing will result in the service re-balancing.

technicalEmails (array of objects, MaxItems: 10). Defines the email addresses that will receive alerts about upcoming maintenance updates or warnings about service instability. See below for nested schema.
terminationProtection (boolean). Prevent service from being deleted. It is recommended to have this enabled for all services.
