I am not sure if this is ever going to be merged, but I feel this code is still very useful for cross-account replication.

The current implementation does not pass AwsCredentials to DDBEmitter, thus replication will always fail. You can remove all constructors and leave the single one looking like this:

    public DynamoDBReplicationEmitter(final DynamoDBStreamsConnectorConfiguration configuration) {
        this.applicationName = configuration.APP_NAME;
        this.endpoint = configuration.DYNAMODB_ENDPOINT;
        this.region = configuration.REGION_NAME;
        this.tableName = configuration.DYNAMODB_DATA_TABLE_NAME;

        AmazonDynamoDBAsync dynamoDBAsync = new AmazonDynamoDBAsyncClient(configuration.AWS_CREDENTIALS_PROVIDER,
                                                                          new ClientConfiguration().withMaxConnections(MAX_THREADS).withRetryPolicy(PredefinedRetryPolicies.DYNAMODB_DEFAULT),
                                                                          Executors.newFixedThreadPool(MAX_THREADS));

        final boolean setDynamoDB = DYNAMODB.compareAndSet(null, dynamoDBAsync);

        if (setDynamoDB && dynamoDBAsync != null) {
            DYNAMODB.get().setEndpoint(endpoint);
        }

        skipErrors = false; // TODO make configurable
    }

Also lombok needs to be updated to 1.18.2 or higher to make the build pass.
