I have been recently involved in a project where I have to leverage the QuickSight APIs and update a dashboard programmatically. I can perform all the other actions but I am unable to update the dashboard from a template. I have tried a couple of different ideas, but all in vain.
Is there anyone who has already worked with the UpdateDashboard API or point me to some detailed documentation where I can understand if I am actually missing anything?
Thanks.
I got this to work using the AWS QuickSight Java V2 API. TO make this work, you need to follow the quick start instructions here:
https://docs.aws.amazon.com/quicksight/latest/user/getting-started.html
You need to get these values:
account - your account number
dashboardId - the dashboard id value
dataSetArn -- the data set ID value
analysisArn - the analysis Arn value
Once you go through the above topics - you will have all of these resource and ready to call UpdateDashboard . Here is the Java example that updates a Dashboard.
package com.example.quicksight;
import software.amazon.awssdk.regions.Region;
import software.amazon.awssdk.services.quicksight.QuickSightClient;
import software.amazon.awssdk.services.quicksight.model.*;
/*
Before running this code example, follow the Getting Started with Data Analysis in Amazon QuickSight located here:
https://docs.aws.amazon.com/quicksight/latest/user/getting-started.html
This code example uses resources that you created by following that topic such as the DataSet Arn value.

I want to add data into kinesis using Sprint Boot Application and React. I am a complete beginner when it comes to Kinesis, AWS, etc. so a beginner friendly guide would be appriciated.
To add data records into an Amazon Kinesis data stream from a Spring BOOT app, you can use the AWS SDK for Java V2 and specifically the Amazon Kinesis Java API. You can use the software.amazon.awssdk.services.kinesis.KinesisClient.
Because you are a beginner, I recommend that you read the AWS SDK Java V2 Developer Guide to become familiar with how to work with this Java API. See Developer guide - AWS SDK for Java 2.x.
Here is a code example that shows you how to add data records using this Service Client. See Github that has the other required classes here.

In my spring boot project, I am first creating a user pool in cognito and then adding a user to the user pool. when adding the user to user pool I need to create a userPoolClient
I am creating the user client with all the required params with
CreateUserPoolClientResponse response = cognitoClient.createUserPoolClient(clientRequest);
but its behaving strangely. when i am running the code its throwing connection pool shut down but when i run my code in debug mode with breakpoint, its able to create the user pool client successfully. I am not sure if creation of connection pool is async process and that's why with the debugger its getting some time before creating it?
Does anyone faced this issue? would appreciate any help. thanks
Try running AWS SDK Java V2 for this use case. Here is the code for V2.

I was trying to find the LanguagePair and Operation associated with a given AWS translate job using the JAVA SDK.
Using the AWS web console, i created a couple of batch jobs to translate a few english sentences to french. In CloudWatch, i could see the metric dimensions as
LanguagePair: en-fr
Operation: TranslateText
Can i retrieve the same information (LanguagePair and Operation) for a given job,
using the TranslateAsyncClient.describeTextTranslationJob(...) method ?
You can use the TranslateClient to describes a translation job given the job number as input. This uses the TranslateClient; however you can use the Async version as well.

I have a S3 bucket xxx. I wrote one lambda function to access data from s3 bucket and writing those details to a RDS PostgreSQL instance. I can do it with my code. I added one trigger to the lambda function for invoking the same when a file falls on s3.
But from my code I can only read file having name 'sampleData.csv'. consider my code given below
public class LambdaFunctionHandler implements RequestHandler<S3Event, String> {
private AmazonS3 s3 = AmazonS3ClientBuilder.standard().build();
public LambdaFunctionHandler() {}
// Test purpose only.
LambdaFunctionHandler(AmazonS3 s3) {
this.s3 = s3;
}
#Override
public String handleRequest(S3Event event, Context context) {
context.getLogger().log("Received event: " + event);
String bucket = "xxx";
String key = "SampleData.csv";
System.out.println(key);
try {
S3Object response = s3.getObject(new GetObjectRequest(bucket, key));
String contentType = response.getObjectMetadata().getContentType();
context.getLogger().log("CONTENT TYPE: " + contentType);
// Read the source file as text
AmazonS3 s3Client = new AmazonS3Client();
String body = s3Client.getObjectAsString(bucket, key);
System.out.println("Body: " + body);
System.out.println();
System.out.println("Reading as stream.....");
System.out.println();
BufferedReader br = new BufferedReader(new InputStreamReader(response.getObjectContent()));
// just saving the excel sheet data to the DataBase
String csvOutput;
try {
Class.forName("org.postgresql.Driver");
Connection con = DriverManager.getConnection("jdbc:postgresql://ENDPOINT:5432/DBNAME","USER", "PASSWORD");
System.out.println("Connected");
// Checking EOF
while ((csvOutput = br.readLine()) != null) {
String[] str = csvOutput.split(",");
String name = str[1];
String query = "insert into schema.tablename(name) values('"+name+"')";
Statement statement = con.createStatement();
statement.executeUpdate(query);
}
System.out.println("Inserted Successfully!!!");
}catch (Exception ase) {
context.getLogger().log(String.format(
"Error getting object %s from bucket %s. Make sure they exist and"
+ " your bucket is in the same region as this function.", key, bucket));
// throw ase;
}
return contentType;
} catch (Exception e) {
e.printStackTrace();
context.getLogger().log(String.format(
"Error getting object %s from bucket %s. Make sure they exist and"
+ " your bucket is in the same region as this function.", key, bucket));
throw e;
}
}
From my code you can see that I mentioned key="SampleData.csv"; is there any way to get the key inside a bucket without specifying a specific file name?
These couple of links would be of help.
http://docs.aws.amazon.com/AmazonS3/latest/dev/ListingKeysHierarchy.html
http://docs.aws.amazon.com/AmazonS3/latest/dev/ListingObjectKeysUsingJava.html
You can list objects using prefix and delimiter to find the key you are looking for without passing a specific filename.
If you need to get the event details on S3, you can actually enable the s3 event notifier to lambda function. Refer the link
You can enable this by,
Click on 'Properties' inside your bucket
Click on 'Events '
Click 'Add notification'
Give a name and select the type of event (eg. Put, delete etc.)
Give prefix and suffix if necessary or else leave blank which consider all events
Then 'Sent to' Lambda function and provide the Lambda ARN.
Now the event details will be sent lambda function as a json format. You can fetch the details from that json. The input will be like this:
{"Records":[{"eventVersion":"2.0","eventSource":"aws:s3","awsRegion":"ap-south-1","eventTime":"2017-11-23T09:25:54.845Z","eventName":"ObjectRemoved:Delete","userIdentity":{"principalId":"AWS:AIDAJASDFGZTLA6UZ7YAK"},"requestParameters":{"sourceIPAddress":"52.95.72.70"},"responseElements":{"x-amz-request-id":"A235BER45D4974E","x-amz-id-2":"glUK9ZyNDCjMQrgjFGH0t7Dz19eBrJeIbTCBNI+Pe9tQugeHk88zHOY90DEBcVgruB9BdU0vV8="},"s3":{"s3SchemaVersion":"1.0","configurationId":"sns","bucket":{"name":"example-bucket1","ownerIdentity":{"principalId":"AQFXV36adJU8"},"arn":"arn:aws:s3:::example-bucket1"},"object":{"key":"SampleData.csv","sequencer":"005A169422CA7CDF66"}}}]}
You can access the key as objectname = event['Records'][0]['s3']['object']['key'](Oops, this is for python)
and then sent this info to RDS.
I am looking for a service to upload videos and images from my mobile applications (frontend). I have heard about Amazon S3 and CloudFront. I am looking for a service that will store them, and will also be able to check if they meet certain criteria (for example, maximum file size of 3MB per picture), and return an error to the client if the file doesn't meet the criteria. Does Amazon S3 or CloudFront provide this? If not, is there any other recommended service for this?
You could use the AWS SDK. Here follows an example of the Java version (Amazon provides SDKs for different languages):
/**
* It stores the given file name in S3 and returns the key under which the file has been stored
* #param resource
* #param bucketName
* #return
*/
public String storeProfileImage(File resource, String bucketName, String username) {
String resourceUrl = null;
if (!resource.exists()) {
throw new IllegalArgumentException("The file " + resource.getAbsolutePath() + " doesn't exist");
}
long lengthInBytes = resource.length();
//For demo purposes. You should use a configurable property for the max size
if (lengthInBytes > (3 * 1024)) {
//Your error handling here
}
AccessControlList acl = new AccessControlList();
acl.grantPermission(GroupGrantee.AllUsers, Permission.Read);
String key = username + "/profilePicture." + FilenameUtils.getExtension(resource.getName());
try {
s3Client.putObject(new PutObjectRequest(bucketName, key, resource).withAccessControlList(acl));
resourceUrl = s3Client.getResourceUrl(bucketName, key);
} catch (AmazonClientException ace) {
LOG.error("A client exception occurred while trying to store the profile" +
" image {} on S3. The profile image won't be stored", resource.getAbsolutePath(), ace);
}
return resourceUrl;
}
You can also perform other operations, e.g. check if the bucket exists before storing the image
/**
* Returns the root URL where the bucket name is located.
* <p>Please note that the URL does not contain the bucket name</p>
* #param bucketName The bucket name
* #return the root URL where the bucket name is located.
*/
public String ensureBucketExists(String bucketName) {
String bucketUrl = null;
try {
if (!s3Client.doesBucketExist(bucketName)) {
LOG.warn("Bucket {} doesn't exists...Creating one");
s3Client.createBucket(bucketName);
LOG.info("Created bucket: {}", bucketName);
}
bucketUrl = s3Client.getResourceUrl(bucketName, null) + bucketName;
} catch (AmazonClientException ace) {
LOG.error("An error occurred while connecting to S3. Will not execute action" +
" for bucket: {}", bucketName, ace);
}
return bucketUrl;
}
