Whether to enable authentication in this cluster. The default is true; it is highly recommended to always leave authentication turned on.

Cassandra is a specification of the Cassandra cluster.

During a migration the operator should alter keyspaces replication settings including the following external DCs.

Medusa defines the desired deployment characteristics for Medusa in this K8ssandraCluster. If this is non-nil, Medusa will be deployed in every Cassandra pod in this K8ssandraCluster.

Reaper defines the desired deployment characteristics for Reaper in this K8ssandraCluster. If this is non-nil, Reaper will be deployed on every Cassandra datacenter in this K8ssandraCluster.

SecretsProvider defines whether the secrets used for credentials and certs will be backed by an external secret backend (e.g. vault).

Stargate defines the desired deployment characteristics for Stargate in this K8ssandraCluster. If this is non-nil, Stargate will be deployed on every Cassandra datacenter in this K8ssandraCluster.

AdditionalSeeds specifies Cassandra node IPs for an existing datacenter. This is primarily intended for migrations from an existing Cassandra cluster that is not managed by k8ssandra-operator.

CDC defines the desired state for CDC integrations. It can be used to feed mutation events from Cassandra into an Apache Pulsar cluster, from where they can be expored to external systems.

Client encryption stores which are used by Cassandra and Reaper.

Override the Cassandra cluster name. If unspecified, the cluster name will be the same as the K8ssandraCluster CRD name.

CassandraConfig contains configuration settings that are applied to cassandra.yaml, dse.yaml and the various jvm*.options files.

Containers defines containers to be deployed in each Cassandra pod.

DatacenterName allows to override the name of the Cassandra datacenter. Kubernetes objects will be named after a sanitized version of it if set, and if not metadata.name.

Racks is a list of named racks. Note that racks are used to create node affinity. //

Resources is the cpu and memory resources for the cassandra container.

Internode encryption stores which are used by Cassandra and Stargate.
