Method Detail

withCoder

public SnsIO.WriteAsync<T> withCoder(Coder<T> elementCoder)

Specify a Coder for SNS PublishRequest object.

Parameters:

elementCoder - Coder

withPublishRequestFn

public SnsIO.WriteAsync<T> withPublishRequestFn(SerializableFunction<T,PublishRequest> publishRequestFn)

Specify a function for converting a message into PublishRequest object.

Parameters:

publishRequestFn - publishRequestFn

withSnsClientProvider

public SnsIO.WriteAsync<T> withSnsClientProvider(SnsAsyncClientProvider asyncClientProvider)

Allows to specify custom SnsAsyncClientProvider. SnsAsyncClientProvider creates new SnsAsyncClientProvider which is later used for writing to a SNS topic.

withSnsClientProvider

public SnsIO.WriteAsync<T> withSnsClientProvider(AwsCredentialsProvider credentialsProvider,
                                                 java.lang.String region)

Specify credential details and region to be used to write to SNS. If you need more sophisticated credential protocol, then you should look at withSnsClientProvider(SnsAsyncClientProvider).

withSnsClientProvider

public SnsIO.WriteAsync<T> withSnsClientProvider(AwsCredentialsProvider credentialsProvider,
                                                 java.lang.String region,
                                                 java.net.URI serviceEndpoint)

Specify credential details and region to be used to write to SNS. If you need more sophisticated credential protocol, then you should look at withSnsClientProvider(SnsAsyncClientProvider).

The serviceEndpoint sets an alternative service host.

expand

public PCollection<org.apache.beam.sdk.io.aws2.sns.SnsResponse<T>> 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).

Specified by:

expand in class PTransform<PCollection<T>,PCollection<org.apache.beam.sdk.io.aws2.sns.SnsResponse<T>>>
