Delete vectors (Java SDK V2)

Permissions

By default, an Alibaba Cloud account has full permissions, while RAM users and RAM roles have none. To grant permissions, the account owner or a RAM administrator must use a RAM policy or a bucket policy.

Sample code

import com.aliyun.sdk.service.oss2.credentials.CredentialsProvider;
import com.aliyun.sdk.service.oss2.credentials.EnvironmentVariableCredentialsProvider;
import com.aliyun.sdk.service.oss2.vectors.OSSVectorsClient;
import com.aliyun.sdk.service.oss2.vectors.models.DeleteVectorsRequest;
import com.aliyun.sdk.service.oss2.vectors.models.DeleteVectorsResult;
import java.util.*;

public class DeleteVectorsSample {
    public static void main(String[] args) throws Exception {
        CredentialsProvider provider = new EnvironmentVariableCredentialsProvider();
        try (OSSVectorsClient client = OSSVectorsClient.newBuilder()
                .region("cn-hangzhou")
                .accountId("1234567890")
                .credentialsProvider(provider)
                .build()) {
            DeleteVectorsRequest request = DeleteVectorsRequest.newBuilder()
                    .bucket("examplebucket")
                    .indexName("exampleindex")
                    .keys(Arrays.asList("key1", "key2"))
                    .build();
            DeleteVectorsResult result = client.deleteVectors(request);
            System.out.printf("status code: %d, request id: %s%n", result.statusCode(), result.requestId());
        }
    }
}
