Method: googleapis.spanner.v1.projects.instances.instancePartitions.patch

Updates an instance partition, and begins allocating or releasing resources as requested. The returned long-running operation can be used to track the progress of updating the instance partition. If the named instance partition does not exist, returns NOT_FOUND. Immediately upon completion of this request: * For resource types for which a decrease in the instance partition'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 partition are rejected. * Reading the instance partition 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 partition's tables. * The instance partition's new resource levels are readable via the API. The returned long-running operation will have a name of the format /operations/ and can be used to track the instance partition modification. The metadata field type is UpdateInstancePartitionMetadata. The response field type is InstancePartition, if successful. Authorization requires spanner.instancePartitions.update permission on the resource name.

This method waits—the workflow execution is paused—until the operation is complete, fails, or times out. The default timeout value is 1800 seconds (30 minutes) and can be changed to a maximum value of 31536000 seconds (one year) for long-running operations using the connector_params field.

The connector uses polling to monitor the long-running operation, which might generate additional billable steps. The polling policy for the long-running operation can be configured. For example, if you set skip_polling to True, the connector invocation call is non-blocking if the initial request succeeds; otherwise, retries might occur.

Arguments

Parameters
name

string

Required. A unique identifier for the instance partition. Values are of the form projects//instances//instancePartitions/a-z*[a-z0-9]. The final segment of the name must be between 2 and 64 characters in length. An instance partition's name cannot be changed after the instance partition is created.
body

object (UpdateInstancePartitionRequest)

Required.

Raised exceptions

Exceptions
ConnectionError In case of a network problem (such as DNS failure or refused connection).
HttpError If the response status is >= 400 (excluding 429 and 503).
TimeoutError If a long-running operation takes longer to finish than the specified timeout limit.
TypeError If an operation or function receives an argument of the wrong type.
ValueError If an operation or function receives an argument of the right type but an inappropriate value. For example, a negative timeout.
OperationError If the long-running operation finished unsuccessfully.
ResponseTypeError If the long-running operation returned a response of the wrong type.

Response

If successful, the response contains an instance of Operation.
