withAwsClientsProvider

public DynamoDBIO.Write<T> withAwsClientsProvider(AwsClientsProvider awsClientsProvider)

withAwsClientsProvider

public DynamoDBIO.Write<T> withAwsClientsProvider(java.lang.String awsAccessKey,
                                                  java.lang.String awsSecretKey,
                                                  com.amazonaws.regions.Regions region,
                                                  java.lang.String serviceEndpoint)

withAwsClientsProvider

public DynamoDBIO.Write<T> withAwsClientsProvider(java.lang.String awsAccessKey,
                                                  java.lang.String awsSecretKey,
                                                  com.amazonaws.regions.Regions region)

withRetryConfiguration

public DynamoDBIO.Write<T> withRetryConfiguration(DynamoDBIO.RetryConfiguration retryConfiguration)

Provides configuration to retry a failed request to publish a set of records to DynamoDB. Users should consider that retrying might compound the underlying problem which caused the initial failure. Users should also be aware that once retrying is exhausted the error is surfaced to the runner which may then opt to retry the current partition in entirety or abort if the max number of retries of the runner is completed. Retrying uses an exponential backoff algorithm, with minimum backoff of 5 seconds and then surfacing the error once the maximum number of retries or maximum configuration duration is exceeded.

Example use:

 DynamoDBIO.write()
   .withRetryConfiguration(DynamoDBIO.RetryConfiguration.create(5, Duration.standardMinutes(1))
   ...
 

Parameters:

retryConfiguration - the rules which govern the retry behavior

Returns:

the DynamoDBIO.Write with retrying configured

withWriteRequestMapperFn

public DynamoDBIO.Write<T> withWriteRequestMapperFn(org.apache.beam.sdk.transforms.SerializableFunction<T,org.apache.beam.sdk.values.KV<java.lang.String,com.amazonaws.services.dynamodbv2.model.WriteRequest>> writeItemMapperFn)

withDeduplicateKeys

public DynamoDBIO.Write<T> withDeduplicateKeys(java.util.List<java.lang.String> deduplicateKeys)
