      • createInstance

        com.google.api.gax.longrunning.OperationFuture<Instance,​CreateInstanceMetadata> createInstance​(InstanceInfo instance)
                                                                                              throws SpannerException
        Creates an instance and begins preparing it to begin serving. The returned Operation can be used to track the progress of preparing the new instance. The instance name is assigned by the caller. If the named instance already exists, a SpannerException is thrown. Immediately upon completion of this request:
        • The instance is readable via the API, with all requested attributes but no allocated resources.
        • Its state is CREATING.
        Until completion of the returned operation:
        • Cancelling the operation renders the instance immediately unreadable via the API.
        • The instance can be deleted.
        • All other attempts to modify the instance are rejected.
        Upon completion of the returned operation:
        • Billing for all successfully-allocated resources begins (some types may have lower than the requested levels).
        • Databases can be created in the instance.
        • The instance's allocated resource levels are readable via the

      • listInstances

        com.google.api.gax.paging.Page<Instance> listInstances​(Options.ListOption... options)
                                                throws SpannerException
        Lists the instances.
        Parameters:
        options - Options to control the instances returned. It also supports Options.filter(String) option. The fields eligible for filtering are:
        • name
        • display_name
        • labels.key where key is the name of a label 
        
 List<Instance> instances =

      • updateInstance

                                                                                                     InstanceInfo.InstanceField... fieldsToUpdate)
        Updates an instance, and begins allocating or releasing resources as requested. The returned Operation can be used to track the progress of updating the instance. If the named instance does not exist, throws SpannerException.

        Immediately upon completion of this request:

        • For resource types for which a decrease in the instance's allocation has been requested, billing is based on the newly-requested level.
        Until completion of the returned operation:
        • Cancelling the operation sets its metadata's [cancel_time][UpdateInstanceMetadata.cancel_time], and begins restoring resources to their pre-request values. The operation is guaranteed to succeed at undoing all resource changes, after which point it terminates with a `CANCELLED` status.
        • All other attempts to modify the instance are rejected.
        • Reading the instance via the API continues to give the pre-request resource levels.
        Upon completion of the returned operation:
        • Billing begins for all successfully-allocated resources (some types may have lower than the requested levels).
        • All newly-reserved resources are available for serving the instance's tables.
        • The instance's new resource levels are readable via the API.

      • getInstanceIAMPolicy

        com.google.cloud.Policy getInstanceIAMPolicy​(String instanceId)
        Returns the IAM policy for the given instance.

      • setInstanceIAMPolicy

        com.google.cloud.Policy setInstanceIAMPolicy​(String instanceId,
                                             com.google.cloud.Policy policy)
        Updates the IAM policy for the given instance and returns the resulting policy. It is highly recommended to first get the current policy and base the updated policy on the returned policy. See Policy.Builder.setEtag(String) for information on the recommended read-modify-write cycle.

      • testInstanceIAMPermissions

        Iterable<String> testInstanceIAMPermissions​(String instanceId,
                                            Iterable<String> permissions)
        Tests for the given permissions on the specified instance for the caller.
        Parameters:
        instanceId - the id of the instance to test.
        permissions - the permissions to test for. Permissions with wildcards (such as '*', 'spanner.*', 'spanner.instances.*') are not allowed.
        Returns:
        the subset of the tested permissions that the caller is allowed.

      • newInstanceBuilder

        Instance.Builder newInstanceBuilder​(InstanceId id)
        Returns a builder for Instance object with the given id.

      • cancelOperation

        void cancelOperation​(String name)
        Cancels the specified long-running operation.

      • getOperation

        com.google.longrunning.Operation getOperation​(String name)
        Gets the specified long-running operation.
