How to use Amazon S3 Transfer Manager in SDKs for large file uploads?

To use Amazon S3 Transfer Manager in SDKs for large file uploads, follow these steps:

Install the AWS SDK for the programming language you are using (e.g. AWS SDK for Java, AWS SDK for Python, etc.).
Configure the AWS SDK with your access key and secret key from your AWS account.
Create an instance of the AmazonS3Client class from the AWS SDK.
Create a TransferManager object using the TransferManagerBuilder class.
Create an Upload object using the TransferManager object's upload method and specify the bucket name, key (file path in S3), and file to upload.

Here is an example in Java using the AWS SDK for Java:

import com.amazonaws.auth.BasicAWSCredentials;
import com.amazonaws.services.s3.AmazonS3;
import com.amazonaws.services.s3.AmazonS3ClientBuilder;
import com.amazonaws.services.s3.transfer.TransferManager;
import com.amazonaws.services.s3.transfer.TransferManagerBuilder;
import com.amazonaws.services.s3.transfer.Upload;

public class S3TransferManagerExample {

    public static void main(String[] args) {
        String accessKeyId = "YOUR_ACCESS_KEY_ID";
        String secretAccessKey = "YOUR_SECRET_ACCESS_KEY";
        String bucketName = "YOUR_BUCKET_NAME";
        String key = "file.txt";
        String filePath = "local_file_path";

        BasicAWSCredentials awsCreds = new BasicAWSCredentials(accessKeyId, secretAccessKey);
        AmazonS3 s3Client = AmazonS3ClientBuilder.standard()
            .withCredentials(new AWSStaticCredentialsProvider(awsCreds))
            .build();
        
        TransferManager transferManager = TransferManagerBuilder.standard()
            .withS3Client(s3Client)
            .build();
        
        Upload upload = transferManager.upload(bucketName, key, new File(filePath));
        
        try {
            upload.waitForCompletion();
            System.out.println("File uploaded successfully");
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
    }
}

Replace YOUR_ACCESS_KEY_ID, YOUR_SECRET_ACCESS_KEY, YOUR_BUCKET_NAME, and local_file_path with your actual credentials, bucket name, and local file path.

This example demonstrates how to use the Amazon S3 Transfer Manager in the AWS SDK for Java to upload a large file to an S3 bucket. You can similarly use the Transfer Manager in other AWS SDKs for different programming languages to achieve large file uploads efficiently.
