Request body

In the request body, supply an instance resource with the following properties:

Property name Value Description Notes
Required Properties
settings nested object The user settings.
settings.settingsVersion long The version of instance settings. This is a required field for update method to make sure concurrent updates are handled properly. During update, use the most recent settingsVersion value for this instance and do not try to update this value.
settings.tier string The tier (or machine type) for this instance, for example db-n1-standard-1 (MySQL instances) or db-custom-1-3840 (PostgreSQL instances). For MySQL instances, this property determines whether the instance is First or Second Generation. For more information, see Instance Settings. writable
Optional Properties
settings.activationPolicy string The activation policy specifies when the instance is activated; it is applicable only when the instance state is RUNNABLE. Valid values:
ALWAYS: The instance is on, and remains so even in the absence of connection requests.
NEVER: The instance is off; it is not activated, even if a connection request arrives.
ON_DEMAND: First Generation instances only. The instance responds to incoming requests, and turns itself off when not in use. Instances with PER_USE pricing turn off after 15 minutes of inactivity. Instances with PER_PACKAGE pricing turn off after 12 hours of inactivity.
settings.authorizedGaeApplications[] list The App Engine app IDs that can access this instance. First Generation instances only. writable
settings.backupConfiguration nested object The daily backup configuration for the instance. writable

settings.backupConfiguration.startTime string Start time for the daily backup configuration in UTC timezone in the 24 hour format - HH:MM. writable
settings.crashSafeReplicationEnabled boolean Configuration specific to read replica instances. Indicates whether database flags for crash-safe replication are enabled. This property is only applicable to First Generation instances. writable
settings.dataDiskSizeGb long The size of data disk, in GB. The data disk size minimum is 10GB. Not used for First Generation instances. writable
settings.databaseFlags[] list The database flags passed to the instance at startup. writable
settings.databaseReplicationEnabled boolean Configuration specific to read replica instances. Indicates whether replication is enabled or not. writable
settings.ipConfiguration nested object The settings for IP Management. This allows to enable or disable the instance IP and manage which external networks can connect to the instance. The IPv4 address cannot be disabled for Second Generation instances. writable
settings.ipConfiguration.authorizedNetworks[] list The list of external networks that are allowed to connect to the instance using the IP. In CIDR notation, also known as 'slash' notation (e.g. writable
settings.ipConfiguration.authorizedNetworks[].expirationTime datetime The time when this access control entry expires in RFC 3339 format, for example 2012-11-15T16:19:00.094Z. writable
settings.ipConfiguration.authorizedNetworks[].name string An optional label to identify this entry. writable
settings.ipConfiguration.authorizedNetworks[].value string The whitelisted value for the access control list. For example, to grant access to a client from an external IP (IPv4 or IPv6) address or subnet, use that address or subnet here. writable
settings.ipConfiguration.ipv4Enabled boolean Whether the instance should be assigned an IP address or not. writable
settings.ipConfiguration.privateNetwork string The resource link for the VPC network from which the Cloud SQL instance is accessible for private IP. For example, /projects/myProject/global/networks/default. This setting can be updated, but it cannot be removed after it is set. writable
settings.ipConfiguration.requireSsl boolean Whether SSL connections over IP should be enforced or not. writable
settings.locationPreference nested object The location preference settings. This allows the instance to be located as near as possible to either an App Engine app or Compute Engine zone for better performance. App Engine co-location is only applicable to First Generation instances. writable
settings.locationPreference.followGaeApplication string The App Engine application to follow, it must be in the same region as the Cloud SQL instance. writable string The preferred Compute Engine zone (e.g. us-central1-a, us-central1-b, etc.). writable
settings.maintenanceWindow nested object The maintenance window for this instance. This specifies when the instance can be restarted for maintenance purposes. Not used for First Generation instances. writable integer day of week (1-7), starting on Monday. writable
settings.maintenanceWindow.hour integer hour of day - 0 to 23. writable
settings.maintenanceWindow.updateTrack string Maintenance timing setting: canary (Earlier) or stable (Later).

settings.pricingPlan string The pricing plan for this instance. This can be either PER_USE or PACKAGE. Only PER_USE is supported for Second Generation instances. writable
settings.replicationType string The type of replication this instance uses. This can be either ASYNCHRONOUS or SYNCHRONOUS. writable
settings.storageAutoResize boolean Configuration to increase storage size automatically. The default value is true. Not used for First Generation instances. writable
settings.storageAutoResizeLimit long The maximum size to which storage capacity can be automatically increased. The default value is 0, which specifies that there is no limit. Not used for First Generation instances. writable
settings.userLabels object User-provided labels, represented as a dictionary where each label is a single key value pair. writable
settings.userLabels.(key) string An individual label entry, composed of a key and a value. writable

Property name Value Description Notes
kind string This is always sql#operation.
targetProject string The project ID of the target instance related to this operation.
targetId string Name of the database instance related to this operation.

status string The status of an operation. Valid values are PENDING, RUNNING, DONE, UNKNOWN.
user string The email address of the user who initiated this operation.
insertTime datetime The time this operation was enqueued in UTC timezone in RFC 3339 format, for example 2012-11-15T16:19:00.094Z.

importContext.uri string Path to the import file in Cloud Storage, in the form gs://bucketName/fileName. Compressed gzip files (.gz) are supported when fileType is SQL. The instance must have write permissions to the bucket and read access to the file.
importContext.database string The target database for the import. If fileType is SQL, this field is required only if the import file does not specify a database, and is overridden by any database specification in the import file. If fileType is CSV, one database must be specified.
importContext.csvImportOptions object Options for importing data as CSV.
importContext.csvImportOptions.table string The table to which CSV data is imported.

If fileType is CSV, you can specify one database, either by using this property or by using the csvExportOptions.selectQuery property, which takes precedence over this property.
PostgreSQL instances: Specify exactly one database to be exported. If fileType is CSV, this database must match the database used in the csvExportOptions.selectQuery property.
exportContext.sqlExportOptions object Options for exporting data as SQL statements.
exportContext.sqlExportOptions.tables[] list Tables to export, or that were exported, from the specified database. If you specify tables, specify one and only one database. For PostgreSQL instances, you can specify only one table.

exportContext.csvExportOptions.selectQuery string The select query used to extract the data.
error.kind string This is always sql#operationErrors.
