Cloud Spanner V1 Client - Class InstanceAdminClient (1.56.0)

Reference documentation and code samples for the Cloud Spanner V1 Client class InstanceAdminClient.

Service Description: Cloud Spanner Instance Admin API

The Cloud Spanner Instance Admin API can be used to create, delete, modify and list instances. Instances are dedicated Cloud Spanner serving and storage resources to be used by Cloud Spanner databases.

Each instance has a "configuration", which dictates where the serving resources for the Cloud Spanner instance are located (e.g., US-central, Europe). Configurations are created by Google based on resource availability.

Cloud Spanner billing is based on the instances that exist and their sizes. After an instance exists, there are no additional per-database or per-operation charges for use of the instance (though there may be additional network bandwidth charges). Instances offer isolation: problems with databases in one instance will not affect other instances. However, within an instance databases can affect each other. For example, if one database in an instance receives a lot of requests and consumes most of the instance resources, fewer resources are available for other databases in that instance, and their performance may suffer.

This class provides the ability to make remote calls to the backing service through method calls that map to API methods. Sample code to get started:

$instanceAdminClient = new InstanceAdminClient();
try {
    $formattedParent = $instanceAdminClient->projectName('[PROJECT]');
    $instanceId = 'instance_id';
    $instance = new Instance();
    $operationResponse = $instanceAdminClient->createInstance($formattedParent, $instanceId, $instance);
    $operationResponse->pollUntilComplete();
    if ($operationResponse->operationSucceeded()) {
        $result = $operationResponse->getResult();
    // doSomethingWith($result)
    } else {
        $error = $operationResponse->getError();
        // handleError($error)
    }
    // Alternatively:
    // start the operation, keep the operation name, and resume later
    $operationResponse = $instanceAdminClient->createInstance($formattedParent, $instanceId, $instance);
    $operationName = $operationResponse->getName();
    // ... do other work
    $newOperationResponse = $instanceAdminClient->resumeOperation($operationName, 'createInstance');
    while (!$newOperationResponse->isDone()) {
        // ... do other work
        $newOperationResponse->reload();
    }
    if ($newOperationResponse->operationSucceeded()) {
        $result = $newOperationResponse->getResult();
    // doSomethingWith($result)
    } else {
        $error = $newOperationResponse->getError();
        // handleError($error)
    }
} finally {
    $instanceAdminClient->close();
}

Many parameters require resource names to be formatted in a particular way. To assist with these names, this class includes a format method for each type of name, and additionally a parseName method to extract the individual identifiers contained within formatted names that are returned by the API.

Methods

instanceName

Formats a string containing the fully-qualified path to represent a instance resource.

Parameters
Name	Description
`project`	`string`
`instance`	`string`

parseName

Parses a formatted name string and returns an associative array of the components in the name.

The following name formats are supported: Template: Pattern

instance: projects/{project}/instances/{instance}
instanceConfig: projects/{project}/instanceConfigs/{instance_config}
project: projects/{project}

The optional $template argument can be supplied to specify a particular pattern, and must match one of the templates listed above. If no $template argument is provided, or if the $template argument does not match one of the templates listed, then parseName will check each of the supported templates, and return the first match.

createInstance

Creates an instance and begins preparing it to begin serving. The returned long-running 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, CreateInstance returns ALREADY_EXISTS.

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 API.
The instance's state becomes READY.

The returned long-running operation will have a name of the format <instance_name>/operations/<operation_id> and can be used to track creation of the instance. The metadata field type is CreateInstanceMetadata. The response field type is Instance, if successful.

Sample code:

$instanceAdminClient = new InstanceAdminClient();
try {
    $formattedParent = $instanceAdminClient->projectName('[PROJECT]');
    $instanceId = 'instance_id';
    $instance = new Instance();
    $operationResponse = $instanceAdminClient->createInstance($formattedParent, $instanceId, $instance);
    $operationResponse->pollUntilComplete();
    if ($operationResponse->operationSucceeded()) {
        $result = $operationResponse->getResult();
    // doSomethingWith($result)
    } else {
        $error = $operationResponse->getError();
        // handleError($error)
    }
    // Alternatively:
    // start the operation, keep the operation name, and resume later
    $operationResponse = $instanceAdminClient->createInstance($formattedParent, $instanceId, $instance);
    $operationName = $operationResponse->getName();
    // ... do other work
    $newOperationResponse = $instanceAdminClient->resumeOperation($operationName, 'createInstance');
    while (!$newOperationResponse->isDone()) {
        // ... do other work
        $newOperationResponse->reload();
    }
    if ($newOperationResponse->operationSucceeded()) {
        $result = $newOperationResponse->getResult();
    // doSomethingWith($result)
    } else {
        $error = $newOperationResponse->getError();
        // handleError($error)
    }
} finally {
    $instanceAdminClient->close();
}

createInstanceConfig

Creates an instance config and begins preparing it to be used. The returned long-running operation can be used to track the progress of preparing the new instance config. The instance config name is assigned by the caller. If the named instance config already exists, CreateInstanceConfig returns ALREADY_EXISTS.

Immediately after the request returns:

The instance config is readable via the API, with all requested attributes. The instance config's reconciling field is set to true. Its state is CREATING.

While the operation is pending:

Cancelling the operation renders the instance config immediately unreadable via the API.
Except for deleting the creating resource, all other attempts to modify the instance config are rejected.

Upon completion of the returned operation:

Instances can be created using the instance configuration.
The instance config's reconciling field becomes false. Its state becomes READY.

The returned long-running operation will have a name of the format <instance_config_name>/operations/<operation_id> and can be used to track creation of the instance config. The metadata field type is CreateInstanceConfigMetadata. The response field type is InstanceConfig, if successful.

Authorization requires spanner.instanceConfigs.create permission on the resource parent.

Sample code:

$instanceAdminClient = new InstanceAdminClient();
try {
    $formattedParent = $instanceAdminClient->projectName('[PROJECT]');
    $instanceConfigId = 'instance_config_id';

deleteInstance

Deletes an instance.

Immediately upon completion of the request:

Billing ceases for all of the instance's reserved resources.

Soon afterward:

The instance and all of its databases immediately and irrevocably disappear from the API. All data in the databases is permanently deleted.

Sample code:

$instanceAdminClient = new InstanceAdminClient();
try {
    $formattedName = $instanceAdminClient->instanceName('[PROJECT]', '[INSTANCE]');
    $instanceAdminClient->deleteInstance($formattedName);
} finally {
    $instanceAdminClient->close();

deleteInstanceConfig

Deletes the instance config. Deletion is only allowed when no instances are using the configuration. If any instances are using the config, returns FAILED_PRECONDITION.

Only user managed configurations can be deleted.

Authorization requires spanner.instanceConfigs.delete permission on the resource name.

Sample code:

$instanceAdminClient = new InstanceAdminClient();
try {

Operations returned are ordered by operation.metadata.value.start_time in descending order starting from the most recently started operation.

Sample code:

$instanceAdminClient = new InstanceAdminClient();
try {
    $formattedParent = $instanceAdminClient->projectName('[PROJECT]');
    // Iterate over pages of elements
    $pagedResponse = $instanceAdminClient->listInstanceConfigOperations($formattedParent);
    foreach ($pagedResponse->iteratePages() as $page) {
        foreach ($page as $element) {
            // doSomethingWith($element);

`optionalArgs`	`array` Optional.
`↳ filter`	`string` An expression that filters the list of returned operations. A filter expression consists of a field name, a comparison operator, and a value for filtering. The value must be a string, a number, or a boolean. The comparison operator must be one of: `<`, `>`, `<=`, `>=`, `!=`, `=`, or `:`. Colon `:` is the contains operator. Filter rules are not case sensitive. The following fields in the Operation are eligible for filtering: * `name` - The name of the long-running operation * `done` - False if the operation is in progress, else true. * `metadata.@type` - the type of metadata. For example, the type string for CreateInstanceConfigMetadata is `type.googleapis.com/google.spanner.admin.instance.v1.CreateInstanceConfigMetadata`. * `metadata.<field_name>` - any field in metadata.value. `metadata.@type` must be specified first, if filtering on metadata fields. * `error` - Error associated with the long-running operation. * `response.@type` - the type of response. * `response.<field_name>` - any field in response.value. You can combine multiple expressions by enclosing each expression in parentheses. By default, expressions are combined with AND logic. However, you can specify AND, OR, and NOT logic explicitly. Here are a few examples: * `done:true` - The operation is complete. * `(metadata.@type=` \ `type.googleapis.com/google.spanner.admin.instance.v1.CreateInstanceConfigMetadata) AND` \ `(metadata.instance_config.name:custom-config) AND` \ `(metadata.progress.start_time < \"2021-03-28T14:50:00Z\") AND` \ `(error:)` - Return operations where: The operation's metadata type is CreateInstanceConfigMetadata. * The instance config name contains "custom-config". * The operation started before 2021-03-28T14:50:00Z. * The operation resulted in an error.

updateInstance

Updates an instance, and begins allocating or releasing resources as requested. The returned long-running operation can be used to track the progress of updating the instance. If the named instance does not exist, returns NOT_FOUND.

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, 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.

The returned long-running operation will have a name of the format <instance_name>/operations/<operation_id> and can be used to track the instance modification. The metadata field type is UpdateInstanceMetadata. The response field type is Instance, if successful.

Authorization requires spanner.instances.update permission on the resource name.

Sample code:

$instanceAdminClient = new InstanceAdminClient();
try {
    $instance = new Instance();
    $fieldMask = new FieldMask();
    $operationResponse = $instanceAdminClient->updateInstance($instance, $fieldMask);
    $operationResponse->pollUntilComplete();
    if ($operationResponse->operationSucceeded()) {
        $result = $operationResponse->getResult();
    // doSomethingWith($result)
    } else {
        $error = $operationResponse->getError();
        // handleError($error)
    }
    // Alternatively:
    // start the operation, keep the operation name, and resume later
    $operationResponse = $instanceAdminClient->updateInstance($instance, $fieldMask);
    $operationName = $operationResponse->getName();
    // ... do other work
    $newOperationResponse = $instanceAdminClient->resumeOperation($operationName, 'updateInstance');
    while (!$newOperationResponse->isDone()) {
        // ... do other work
        $newOperationResponse->reload();
    }
    if ($newOperationResponse->operationSucceeded()) {
        $result = $newOperationResponse->getResult();
    // doSomethingWith($result)
    } else {
        $error = $newOperationResponse->getError();
        // handleError($error)
    }
} finally {
    $instanceAdminClient->close();
}

Parameters
Name	Description
`instance`	`Google\Cloud\Spanner\Admin\Instance\V1\Instance` Required. The instance to update, which must always include the instance name. Otherwise, only fields mentioned in field_mask need be included.
`fieldMask`	`Google\Protobuf\FieldMask` Required. A mask specifying which fields in Instance should be updated. The field mask must always be specified; this prevents any future fields in Instance from being erased accidentally by clients that do not know about them.
`optionalArgs`	`array` Optional.
`↳ retrySettings`	`RetrySettings\|array` Retry settings to use for this call. Can be a Google\ApiCore\RetrySettings object, or an associative array of retry settings parameters. See the documentation on Google\ApiCore\RetrySettings for example usage.

Returns
Type	Description
`Google\ApiCore\OperationResponse`

updateInstanceConfig

Updates an instance config. The returned long-running operation can be used to track the progress of updating the instance. If the named instance config does not exist, returns NOT_FOUND.

Only user managed configurations can be updated.

Immediately after the request returns:

The instance config's reconciling field is set to true.

While the operation is pending:

Cancelling the operation sets its metadata's cancel_time. The operation is guaranteed to succeed at undoing all changes, after which point it terminates with a CANCELLED status.
All other attempts to modify the instance config are rejected.
Reading the instance config via the API continues to give the pre-request values.

Upon completion of the returned operation:

Creating instances using the instance configuration uses the new values.
The instance config's new values are readable via the API.
The instance config's reconciling field becomes false.

The returned long-running operation will have a name of the format <instance_config_name>/operations/<operation_id> and can be used to track the instance config modification. The metadata field type is UpdateInstanceConfigMetadata. The response field type is InstanceConfig, if successful.

Authorization requires spanner.instanceConfigs.update permission on the resource name.

Sample code:

$instanceAdminClient = new InstanceAdminClient();
try {
    $instanceConfig = new InstanceConfig();
    $updateMask = new FieldMask();
    $operationResponse = $instanceAdminClient->updateInstanceConfig($instanceConfig, $updateMask);
    $operationResponse->pollUntilComplete();
    if ($operationResponse->operationSucceeded()) {
        $result = $operationResponse->getResult();
    // doSomethingWith($result)
    } else {
        $error = $operationResponse->getError();
        // handleError($error)
    }
    // Alternatively:
    // start the operation, keep the operation name, and resume later
    $operationResponse = $instanceAdminClient->updateInstanceConfig($instanceConfig, $updateMask);
    $operationName = $operationResponse->getName();
    // ... do other work
    $newOperationResponse = $instanceAdminClient->resumeOperation($operationName, 'updateInstanceConfig');
    while (!$newOperationResponse->isDone()) {
        // ... do other work
        $newOperationResponse->reload();
    }
    if ($newOperationResponse->operationSucceeded()) {
        $result = $newOperationResponse->getResult();
    // doSomethingWith($result)
    } else {
        $error = $newOperationResponse->getError();
        // handleError($error)
    }
} finally {
    $instanceAdminClient->close();
}

Parameters
Name	Description
`instanceConfig`	`Google\Cloud\Spanner\Admin\Instance\V1\InstanceConfig` Required. The user instance config to update, which must always include the instance config name. Otherwise, only fields mentioned in update_mask need be included. To prevent conflicts of concurrent updates, etag can be used.
`updateMask`	`Google\Protobuf\FieldMask` Required. A mask specifying which fields in InstanceConfig should be updated. The field mask must always be specified; this prevents any future fields in InstanceConfig from being erased accidentally by clients that do not know about them. Only display_name and labels can be updated.
`optionalArgs`	`array` Optional.
`↳ validateOnly`	`bool` An option to validate, but not actually execute, a request, and provide the same response.
`↳ retrySettings`	`RetrySettings\|array` Retry settings to use for this call. Can be a Google\ApiCore\RetrySettings object, or an associative array of retry settings parameters. See the documentation on Google\ApiCore\RetrySettings for example usage.

Returns
