Returns

Type Description

Promise <[ protos. google.cloud.datafusion.v1.IVersion [], protos. google.cloud.datafusion.v1.IListAvailableVersionsRequest | null, protos. google.cloud.datafusion.v1.IListAvailableVersionsResponse ]>

{Promise} - The promise which resolves to an array. The first element of the array is Array of [Version]. The client library will perform auto-pagination by default: it will call the API as many times as needed and will merge results from all the pages into this array. Note that it can affect your quota. We recommend using listAvailableVersionsAsync() method described below for async iteration which you can stop as needed.

Restart a single Data Fusion instance. At the end of an operation instance is fully restarted.

Parameters

Name	Description
request	`protos. google.cloud.datafusion.v1.IRestartInstanceRequest` The request object that will be sent.
options	`CallOptions` Call options. See CallOptions for more details.

Returns

Type	Description
Promise <[ LROperation <protos. google.cloud.datafusion.v1.IInstance , protos. google.cloud.datafusion.v1.IOperationMetadata >, protos. google.longrunning.IOperation \| undefined, {} \| undefined ]>	{Promise} - The promise which resolves to an array. The first element of the array is an object representing a long running operation. Its `promise()` method returns a promise you can `await` for. Please see the [documentation](https://github.com/googleapis/gax-nodejs/blob/master/client-libraries.md#long-running-operations) for more details and examples.
