Example

Java

import io.milvus.v2.client.ConnectConfig;
import io.milvus.v2.client.MilvusClientV2;
import io.milvus.v2.service.utility.request.CompactReq;
import io.milvus.v2.service.utility.request.GetCompactionStateReq;
import io.milvus.v2.service.utility.response.CompactResp;
import io.milvus.v2.service.utility.response.GetCompactionStateResp;

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

MilvusClientV2 client = new MilvusClientV2(connectConfig);

// 2. Compact a collection
client.compact(CompactReq.builder()
    .collectionName("my_collection")
    .build();
);

// 3. Get the compaction status
client.getCompactionState(GetCompactionStateReq.builder()
