Example

import io.milvus.v2.client.ConnectConfig;
import io.milvus.v2.client.MilvusClientV2;
import io.milvus.v2.service.partition.request.LoadPartitionsReq;

// 1. Set up a client
ConnectConfig connectConfig = ConnectConfig.builder()
        .uri("http://localhost:19530")
        .token("root:Milvus")
        .build();
        
MilvusClientV2 client = new MilvusClientV2(connectConfig);

// 2. Load partition in collection
LoadPartitionsReq loadPartitionsReq = LoadPartitionsReq.builder()
        .collectionName("test")
        .partitionNames(Collections.singletonList("test_partition"))
        .build();
client.loadPartitions(loadPartitionsReq);
