Cloud Data Fusion API v1 - Package cloud.google.com/go/datafusion/apiv1 (v1.8.7)
Package datafusion is an auto-generated package for theCloud Data Fusion API.
Cloud Data Fusion is a fully-managed, cloud native, enterprise dataintegration service for quickly building and managing data pipelines. Itprovides a graphical interface to increase time efficiency and reducecomplexity, and allows business users, developers, and data scientists toeasily and reliably build scalable data integration solutions to cleanse,prepare, blend, transfer and transform data without having to wrestle withinfrastructure.
General documentation
For information that is relevant for all client libraries please referencehttps://pkg.go.dev/cloud.google.com/go#pkg-overview. Some information on thispage includes:
- Authentication and Authorization
- Timeouts and Cancellation
- Testing against Client Libraries
- Debugging Client Libraries
- Inspecting errors
Example usage
To get started with this package, create a client.
// go get cloud.google.com/go/datafusion/apiv1@latestctx:=context.Background()// This snippet has been automatically generated and should be regarded as a code template only.// It will require modifications to work:// - It may require correct/in-range values for request initialization.// - It may require specifying regional endpoints when creating the service client as shown in:// https://pkg.go.dev/cloud.google.com/go#hdr-Client_Optionsc,err:=datafusion.NewClient(ctx)iferr!=nil{// TODO: Handle error.}deferc.Close()
The client will use your default application credentials. Clients should be reused instead of created as needed.The methods of Client are safe for concurrent use by multiple goroutines.The returned client must be Closed when it is done being used.
Using the Client
The following is an example of making an API call with the newly created client, mentioned above.
req:=&datafusionpb.CreateInstanceRequest{// TODO: Fill request struct fields.// See https://pkg.go.dev/cloud.google.com/go/datafusion/apiv1/datafusionpb#CreateInstanceRequest.}op,err:=c.CreateInstance(ctx,req)iferr!=nil{// TODO: Handle error.}resp,err:=op.Wait(ctx)iferr!=nil{// TODO: Handle error.}// TODO: Use resp._=resp
Use of Context
The ctx passed to NewClient is used for authentication requests andfor creating the underlying connection, but is not used for subsequent calls.Individual methods on the client use the ctx given to them.
To close the open connection, use the Close() method.
Functions
func DefaultAuthScopes
funcDefaultAuthScopes()[]stringDefaultAuthScopes reports the default set of authentication scopes to use with this package.
CallOptions
typeCallOptionsstruct{ListAvailableVersions[]gax.CallOptionListInstances[]gax.CallOptionGetInstance[]gax.CallOptionCreateInstance[]gax.CallOptionDeleteInstance[]gax.CallOptionUpdateInstance[]gax.CallOptionRestartInstance[]gax.CallOption}CallOptions contains the retry settings for each method of Client.

However, fields must not be modified concurrently with method calls.
Service for creating and managing Data Fusion instances.Data Fusion enables ETL developers to build code-free, data integrationpipelines via a point-and-click UI.
func NewClient
NewClient creates a new data fusion client based on gRPC.The returned client must be Closed when it is done being used to clean up its underlying connections.
