Create a vector index (Java SDK V2)

Permissions

By default, an Alibaba Cloud account has full permissions. RAM users and RAM roles have no permissions by default. The Alibaba Cloud account owner or an administrator must grant the required permissions by using 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.PutVectorIndexRequest;
import com.aliyun.sdk.service.oss2.vectors.models.PutVectorIndexResult;

public class PutVectorIndexSample {
    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()) {
            PutVectorIndexRequest request = PutVectorIndexRequest.newBuilder()
                    .bucket("examplebucket")
                    .indexName("exampleindex")
                    .dataType("float32")
                    .dimension(3)
                    .distanceMetric("cosine")
                    .build();
            PutVectorIndexResult result = client.putVectorIndex(request);
            System.out.printf("status code: %d, request id: %s%n", result.statusCode(), result.requestId());
        }
    }
}
