We Keep Coding

Can we use the same instance of AWS S3 TransferManager or should we create a new instance for each file upload?

I am using a Spring Boot app to expose an API tasked with uploading file to AWS S3.
I am using a single instance of S3 client in the application:
#Bean
public AmazonS3 s3Client() {
BasicAWSCredentials credentials = new BasicAWSCredentials(awsAccessKey, awsSecretAccessKey);
AmazonS3ClientBuilder amazonS3ClientBuilder = AmazonS3ClientBuilder
.standard()
.withCredentials(new AWSStaticCredentialsProvider(credentials))
.withEndpointConfiguration(
new AwsClientBuilder.EndpointConfiguration(
endpointUrl, Regions.EU_WEST_1.getName()));
return amazonS3ClientBuilder.build();
}
Can I create a bean for TransferManager in a similar fashion and reuse the same instance across requests or do I need to create a fresh instance for every API call to upload a file?
What is the recommended practice here?

The recommended practice is to move away from AWS SDK for Java V1. Amazon recommends that you use AWS SDK for Java V2. Now to upload content to an Amazon S3 bucket, you can use the S3TransferManager.
If you are not familiar with using the V2 SDK, I recommend that you read the Developer Guide.
Here is a code example of how to use this to upload an object. And you can use the same instance to upload different objects. All you need to do is to set to pass the correct the values to transferManager.uploadFile().
package com.example.transfermanager;
import software.amazon.awssdk.auth.credentials.EnvironmentVariableCredentialsProvider;
import software.amazon.awssdk.auth.credentials.ProfileCredentialsProvider;
import software.amazon.awssdk.regions.Region;
import software.amazon.awssdk.transfer.s3.FileUpload;
import software.amazon.awssdk.transfer.s3.S3TransferManager;
import java.nio.file.Paths;
/**

*/
public class UploadObject {
public static void main(String[] args) {
final String usage = "\n" +
"Usage:\n" +
" <bucketName> <objectKey> <objectPath> \n\n" +
"Where:\n" +
" bucketName - The Amazon S3 bucket to upload an object into.\n" +
" objectKey - The object to upload (for example, book.pdf).\n" +
" objectPath - The path where the file is located (for example, C:/AWS/book2.pdf). \n\n" ;
if (args.length != 3) {
System.out.println(usage);
System.exit(1);
}
long mb = 1024;
String bucketName = args[0];
String objectKey = args[1];
String objectPath = args[2];
System.out.println("Putting an object into bucket "+bucketName +" using the S3TransferManager");
ProfileCredentialsProvider credentialsProvider = ProfileCredentialsProvider.create();
Region region = Region.US_EAST_1;
S3TransferManager transferManager = S3TransferManager.builder()
.s3ClientConfiguration(cfg ->cfg.region(region)
.credentialsProvider(credentialsProvider)
.targetThroughputInGbps(20.0)
.minimumPartSizeInBytes(10 * mb))
.build();
uploadObjectTM(transferManager, bucketName, objectKey, objectPath);
System.out.println("Object was successfully uploaded using the Transfer Manager.");
transferManager.close();
}
public static void uploadObjectTM( S3TransferManager transferManager, String bucketName, String objectKey, String objectPath) {
FileUpload upload =
transferManager.uploadFile(u -> u.source(Paths.get(objectPath))
.putObjectRequest(p -> p.bucket(bucketName).key(objectKey)));
upload.completionFuture().join();
}
}
UPDATE
As the above API still appears to be in Preview Mode (judging from Maven repo):
https://mvnrepository.com/artifact/software.amazon.awssdk/s3-transfer-manager
You can use the Amazon S3 V2 Service Client to upload objects. V2 is still better practice then V1.
You can use this code:
package com.example.s3;
// snippet-start:[s3.java2.s3_object_upload.import]
import software.amazon.awssdk.auth.credentials.ProfileCredentialsProvider;
import software.amazon.awssdk.core.sync.RequestBody;

import java.io.File;

looking for a sample code to read parameter value from aws parameter store

looking for a sample java code to read parameter store values like RDS connection string from aws parameter store. appreicate code or any reference links. thanks.

Here is the V2 (not V1) example to read a specific parameter value from the AWS parameter store:
import software.amazon.awssdk.regions.Region;
import software.amazon.awssdk.services.ssm.SsmClient;
import software.amazon.awssdk.services.ssm.model.GetParameterRequest;
import software.amazon.awssdk.services.ssm.model.GetParameterResponse;
import software.amazon.awssdk.services.ssm.model.SsmException;
public class GetParameter {
public static void main(String[] args) {
final String USAGE = "\n" +

" GetParameter <paraName>\n\n" +
"Where:\n" +
" paraName - the name of the parameter\n";
if (args.length < 1) {
System.out.println(USAGE);
System.exit(1);
}
// Get args
String paraName = args[0];
Region region = Region.US_EAST_1;
SsmClient ssmClient = SsmClient.builder()
.region(region)
.build();
try {
GetParameterRequest parameterRequest = GetParameterRequest.builder()
.name(paraName)
.build();
GetParameterResponse parameterResponse = ssmClient.getParameter(parameterRequest);
System.out.println("The parameter value is "+parameterResponse.parameter().value());
} catch (SsmException e) {
System.err.println(e.getMessage());
System.exit(1);
}
}
}

import com.amazonaws.services.simplesystemsmanagement.AWSSimpleSystemsManagement;
import com.amazonaws.services.simplesystemsmanagement.AWSSimpleSystemsManagementClientBuilder;

import com.amazonaws.services.simplesystemsmanagement.model.GetParametersResult;
...
private static AWSSimpleSystemsManagement ssmclient = AWSSimpleSystemsManagementClientBuilder

...
GetParametersRequest paramRequest = new GetParametersRequest()
.withNames(parameterName).withWithDecryption(encrypted);
GetParametersResult paramResult = new GetParametersResult();
paramResult = ssmclient.getParameters(paramRequest);

I think GitHub may be of help. I searched for SsmClient getParameter language:java and some of the results seem promising.
This one for example:
public static String getDiscordToken(SsmClient ssmClient) {
GetParameterRequest request = GetParameterRequest.builder().
name("/discord/token").
withDecryption(Boolean.TRUE).
build();
GetParameterResponse response = ssmClient.getParameter(request);
return response.parameter().value();
}

Sending PubSub message manually in Dataflow

How can I send a PubSub message manually (that is to say, without using a PubsubIO) in Dataflow ?
Importing (via Maven) google-cloud-dataflow-java-sdk-all 2.5.0 already imports a version of com.google.pubsub.v1 for which I was unable to find an easy way to send messages to a Pubsub topic (this version doesn't, for instance, allow to manipulate Publisher instances, which is the way described in the official documentation).

Would you consider using PubsubUnboundedSink? Quick example:
import org.apache.beam.runners.dataflow.options.DataflowPipelineOptions;
import org.apache.beam.sdk.options.PipelineOptionsFactory;
import org.apache.beam.sdk.options.ValueProvider.StaticValueProvider;
import org.apache.beam.sdk.Pipeline;
import org.apache.beam.sdk.transforms.DoFn;
import org.apache.beam.sdk.transforms.ParDo;
import org.apache.beam.sdk.transforms.Create;
import org.apache.beam.sdk.values.PCollection;
import org.apache.beam.sdk.io.gcp.pubsub.PubsubClient;
import org.apache.beam.sdk.io.gcp.pubsub.PubsubJsonClient;
import org.apache.beam.sdk.io.gcp.pubsub.PubsubUnboundedSink;
import org.apache.beam.sdk.io.gcp.pubsub.PubsubClient.TopicPath;
import org.apache.beam.sdk.io.gcp.pubsub.PubsubMessage;
public class PubsubTest {
public static void main(String[] args) {
DataflowPipelineOptions options = PipelineOptionsFactory.fromArgs(args)
.as(DataflowPipelineOptions.class);
// writes message to "output_topic"
TopicPath topic = PubsubClient.topicPathFromName(options.getProject(), "output_topic");
Pipeline p = Pipeline.create(options);
p
.apply("input string", Create.of("This is just a message"))
.apply("convert to Pub/Sub message", ParDo.of(new DoFn<String, PubsubMessage>() {
#ProcessElement
public void processElement(ProcessContext c) {
c.output(new PubsubMessage(c.element().getBytes(), null));
}
}))
.apply("write to topic", new PubsubUnboundedSink(
PubsubJsonClient.FACTORY,
StaticValueProvider.of(topic), // topic
"timestamp", // timestamp attribute
"id", // ID attribute
5 // number of shards
));
p.run();
}
}

Here's a way I found browsing https://github.com/GoogleCloudPlatform/cloud-pubsub-samples-java/blob/master/dataflow/src/main/java/com/google/cloud/dataflow/examples/StockInjector.java:
import com.google.api.services.pubsub.Pubsub;

private final Sleeper sleeper;
private RetryHttpInitializerWrapper(GoogleCredential wrappedCredential) {
this(wrappedCredential, Sleeper.DEFAULT);
}
// Use only for testing.
RetryHttpInitializerWrapper(
GoogleCredential wrappedCredential, Sleeper sleeper) {
this.wrappedCredential = Preconditions.checkNotNull(wrappedCredential);
this.sleeper = sleeper;
}
#Override
public void initialize(HttpRequest request) {
final HttpUnsuccessfulResponseHandler backoffHandler =
new HttpBackOffUnsuccessfulResponseHandler(
new ExponentialBackOff())

request.setInterceptor(wrappedCredential);
request.setUnsuccessfulResponseHandler(
new HttpUnsuccessfulResponseHandler() {
#Override

boolean supportsRetry)
throws IOException {
if (wrappedCredential.handleResponse(request,
response,
supportsRetry)) {
// If credential decides it can handle it, the

// specific to authentication, and no backoff is
// desired.
return true;
} else if (backoffHandler.handleResponse(request,
response,
supportsRetry)) {
// Otherwise, we defer to the judgement of our
// internal backoff handler.
logger.info("Retrying " + request.getUrl());
return true;
} else {
return false;
}
}
});
request.setIOExceptionHandler(new HttpBackOffIOExceptionHandler(
new ExponentialBackOff()).setSleeper(sleeper));
}
}
/**

return new Pubsub.Builder(transport, JSON_FACTORY, initializer).build();
} catch (IOException | GeneralSecurityException e) {

// Publish message to Pubsub.
PubsubMessage pubsubMessage = new PubsubMessage();
pubsubMessage.encodeData(message.getBytes());
PublishRequest publishRequest = new PublishRequest();
publishRequest.setMessages(Collections.singletonList(pubsubMessage));
try {
pubsub.projects().topics().publish(outputTopic, publishRequest).execute();
} catch (java.io.IOException e) {
logger.error("Stuff happened in pubsub: " + e);
}
}
}

You can send pubsub message using PubsubIO writeMessages method
dataflow Pipeline steps
Pipeline p = Pipeline.create(options);
p.apply("Transformer1", ParDo.of(new Fn.method1()))
.apply("Transformer2", ParDo.of(new Fn.method2()))
.apply("PubsubMessageSend", PubsubIO.writeMessages().to(PubSubConfig.getTopic(options.getProject(), options.getpubsubTopic ())));
Define Project Name and pubsubTopic where to want to send pub subs message in the PipeLineOptions

VertX3 verticle deployment: CompletionHandler not triggered

When I run the following piece of code:
import io.vertx.core.*;
import io.vertx.core.eventbus.MessageConsumer;
import io.vertx.core.json.JsonObject;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
class TestVerticle extends AbstractVerticle {
final Logger logger = LoggerFactory.getLogger(TestVerticle.class.getName());
public static final String ADDRESS = "oot.test";
public void start(Future<Void> startFuture) {
logger.info("starting test verticle");
MessageConsumer<JsonObject> consumer = vertx.eventBus().consumer(ADDRESS);
consumer.handler(message -> {
final JsonObject body = message.body();
logger.info("received: " + body);
JsonObject replyMessage = body.copy();
replyMessage.put("status", "processed");
message.reply(replyMessage);
});
logger.info("started test verticle");
}
}
public class Scratchpad {
private final static Logger logger = LoggerFactory.getLogger(Scratchpad.class);
public static void main(String[] args) throws InterruptedException {
Vertx vertx = Vertx.vertx();
logger.info("deploying test verticle");
Handler<AsyncResult<String>> completionHandler = result -> {
System.out.println("done");
if (result.succeeded()) {
logger.info("deployment result: " + result.result());
} else {
logger.error("failed to deploy: " + result);
}
};
TestVerticle testVerticle = new TestVerticle();
vertx.deployVerticle(testVerticle, completionHandler);
logger.info("deployment completed");
}
}
I expect the CompletionHandler content to be executed and therefore I should get something sent to stdout (at least "done", although the logging should be working as well) but nothing happens. All the other logging information shows up correctly on my screen. What am I doing wrong?

After:
logger.info("started test verticle");
Add:
startFuture.complete();
See Asynchronous Verticle start and stop section of the docs about the asynchronous start method:
This version of the method takes a Future as a parameter. When the method returns the verticle will not be considered deployed.
Some time later, after you've done everything you need to do (e.g. start other verticles), you can call complete on the Future (or fail) to signal that you're done.

I verified following code below which is working through fiddler proxy. Thanks to how to Capture https with fiddler, in java post which gave me hints:
System.setProperty("http.proxyHost", "127.0.0.1");
System.setProperty("https.proxyHost", "127.0.0.1");
System.setProperty("http.proxyPort", "8888");
System.setProperty("https.proxyPort", "8888");
System.setProperty("javax.net.ssl.trustStore", "C:\\Program Files\\Java\\jdk1.8.0_102\\bin\\FiddlerKeyStore");
System.setProperty("javax.net.ssl.trustStorePassword", "mypassword");

For others who face issue like me we can connect to azure mediaservices using network proxy by using below code
// Set up the MediaContract object to call into the Media Services account
Configuration configuration = MediaConfiguration.configureWithOAuthAuthentication(
mediaServiceUri, oAuthUri, clientId, clientSecret, scope);
configuration.getProperties().put(Configuration.PROPERTY_HTTP_PROXY_HOST, "Hostvalue");
configuration.getProperties().put(Configuration.PROPERTY_HTTP_PROXY_PORT, "Portvalue");
configuration.getProperties().put(Configuration.PROPERTY_HTTP_PROXY_SCHEME, "http");
MediaContract mediaService = MediaService.create(configuration);
Now use the mediaService to perform other operations.
