public Write()

Method Details

withTopicArn

public SnsIO.Write<T> withTopicArn(String topicArn)

SNS topic ARN used for publishing to SNS.

The topic ARN is optional. If set, its existence will be validated and the SNS publish request will be configured accordingly.

withPublishRequestBuilder

public SnsIO.Write<T> withPublishRequestBuilder(SerializableFunction<T,PublishRequest.Builder> requestBuilder)

Function to convert a message into a PublishRequest.Builder (mandatory).

If an SNS topic arn is set, it will be automatically set on the PublishRequest.Builder.

withPublishRequestFn

@Deprecated
public SnsIO.Write<T> withPublishRequestFn(SerializableFunction<T,PublishRequest> publishRequestFn)

Deprecated.

Use withPublishRequestBuilder(SerializableFunction) instead.

Specify a function for converting a message into PublishRequest object.

withClientConfiguration

public SnsIO.Write<T> withClientConfiguration(ClientConfiguration config)

Configuration of SNS client.

expand

public PCollection<PublishResponse> expand(PCollection<T> input)

Description copied from class: PTransform

Override this method to specify how this PTransform should be expanded on the given InputT.

NOTE: This method should not be called directly. Instead apply the PTransform should be applied to the InputT using the apply method.

Composite transforms, which are defined in terms of other transforms, should return the output of one of the composed transforms. Non-composite transforms, which do not apply any transforms internally, should return a new unbound output and register evaluators (via backend-specific registration methods).
