A Bucket is the globally unique namespace in TOS, functioning as a data container used to store Object data. When you no longer need to retain a bucket (Bucket), you may delete it to avoid incurring additional charges. This document describes how to delete a specified bucket using the TOS Java SDK deleteBucket interface.
Category
- Once a bucket is deleted, it cannot be recovered. Please proceed with caution.
- Before deleting a bucket, you must have the tos:DeleteBucket permission. For detailed instructions, please refer to Permission Configuration Overview.
Prerequisites
Before deleting a bucket, ensure that all data within the bucket has been removed.
- If versioning is enabled for the bucket, please ensure that all current and previous version objects within the bucket have been deleted. For detailed instructions, see Delete Object.
- If there are unmerged shards in the bucket, ensure that all shard data is deleted. For detailed instructions, see Delete Shard.
- If there are a large number of objects in the bucket, you can configure lifecycle rules to enable batch deletion of objects. For specific steps, see Configuring Lifecycle Rules.
Code Example
The following code demonstrates how to delete an empty bucket.
import com.volcengine.tos.TOSV2;
import com.volcengine.tos.TOSV2ClientBuilder;
import com.volcengine.tos.TosClientException;
import com.volcengine.tos.TosServerException;
import com.volcengine.tos.model.bucket.DeleteBucketInput;
import com.volcengine.tos.model.bucket.DeleteBucketOutput;
public class DeleteBucketExample {
public static void main(String[] args) {
String endpoint = "your endpoint";
String region = "your region";
String accessKey = System.getenv("TOS_ACCESS_KEY");
String secretKey = System.getenv("TOS_SECRET_KEY");
String bucketName = "your bucket name";
TOSV2 tos = new TOSV2ClientBuilder().build(region, endpoint, accessKey, secretKey);
try{
DeleteBucketInput input = new DeleteBucketInput().setBucket(bucketName);
DeleteBucketOutput output = tos.deleteBucket(input);
System.out.println("deleteBucket succeed, " + output);
} catch (TosClientException e) {
System.out.println("deleteBucket failed");
System.out.println("Message: " + e.getMessage());
if (e.getCause() != null) {
e.getCause().printStackTrace();
}
} catch (TosServerException e) {
System.out.println("deleteBucket failed");
System.out.println("StatusCode: " + e.getStatusCode());
System.out.println("Code: " + e.getCode());
System.out.println("Message: " + e.getMessage());
System.out.println("RequestID: " + e.getRequestID());
} catch (Throwable t) {
System.out.println("deleteBucket failed");
System.out.println("unexpected exception, message: " + t.getMessage());
}
}
}
