compact()

This operation compacts the collection by merging small segments into larger ones. It is recommended to call this operation after inserting a large amount of data into a collection.

public CompactResp compact(CompactReq request)

Request Syntax

compact(CompactReq.builder()
    .databaseName(String databaseName)
    .collectionName(String collectionName)
    .isClustering(Boolean isClustering)
    .isL0(Boolean isL0)
    .build()
);

BUILDER METHODS:

• databaseName(String databaseName)

  The name of the database. Defaults to the current database if not specified.

• collectionName(String collectionName)

  The name of the target collection.

• isClustering(Boolean isClustering)

  Whether to perform clustering compaction. Defaults to Boolean.FALSE.

• isL0(Boolean isL0)

  Whether to request L0 compaction. Defaults to Boolean.FALSE and is independent from clustering compaction.

RETURNS:

CompactResp

A CompactResp object contains a compaction ID.

EXCEPTIONS:

• MilvusClientException

  This exception will be raised when any error occurs during this operation.

Example

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.response.CompactResp;

// 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();
);
