Example 1 with AmazonDynamoDBStreamsAdapterClient

use of com.amazonaws.services.dynamodbv2.streamsadapter.AmazonDynamoDBStreamsAdapterClient in project flink by apache.

the class DynamoDBStreamsProxy method createKinesisClient.

/**
 * Creates an AmazonDynamoDBStreamsAdapterClient. Uses it as the internal client interacting
 * with the DynamoDB streams.
 *
 * @param configProps configuration properties
 * @return an AWS DynamoDB streams adapter client
 */
@Override
protected AmazonKinesis createKinesisClient(Properties configProps) {
    ClientConfiguration awsClientConfig = new ClientConfigurationFactory().getConfig();
    setAwsClientConfigProperties(awsClientConfig, configProps);
    AWSCredentialsProvider credentials = getCredentialsProvider(configProps);
    awsClientConfig.setUserAgentPrefix(String.format(USER_AGENT_FORMAT, EnvironmentInformation.getVersion(), EnvironmentInformation.getRevisionInformation().commitId));
    AmazonDynamoDBStreamsAdapterClient adapterClient = new AmazonDynamoDBStreamsAdapterClient(credentials, awsClientConfig);
    if (configProps.containsKey(AWS_ENDPOINT)) {
        adapterClient.setEndpoint(configProps.getProperty(AWS_ENDPOINT));
    } else {
        adapterClient.setRegion(Region.getRegion(Regions.fromName(configProps.getProperty(AWS_REGION))));
