insert()

A MilvusClient interface. This method inserts entities into a specified collection.

R<InsertResponse> insert(InsertRowsParam requestParam);

InsertRowsParam

Use the InsertRowsParam.Builder method to construct an InsertRowsParam object.

import io.milvus.param.highlevel.dml.InsertRowsParam;
InsertRowsParam.Builder builder = InsertRowsParam.newBuilder();

Methods of InsertRowsParam.Builder:

The InsertRowsParam.Builder.build() method can throw the following exceptions:

• ParamException is raised if the parameter is invalid.

Returns

This method catches all the exceptions and returns an R<InsertResponse> object.

• If the API fails on the server side, it returns the error code and message from the server.
• If the API fails by RPC exception, it returns R.Status.Unknow and the error message of the exception.
• If the API succeeds, it returns a valid InsertResponse held by the R template.

Example

import io.milvus.param.*;
import io.milvus.response.MutationResultWrapper;
import io.milvus.grpc.MutationResult;

List<JSONObject> rowsData = new ArrayList<>();
Random ran = new Random();
for (long i = 0L; i < rowCount; ++i) {
    JSONObject row = new JSONObject();
    row.put(AGE_FIELD, ran.nextInt(99));
    row.put(VECTOR_FIELD, generateFloatVector());

    // $meta if collection EnableDynamicField, you can input this field not exist in schema, else deny
    row.put(INT32_FIELD_NAME, ran.nextInt());
    row.put(INT64_FIELD_NAME, ran.nextLong());
    row.put(VARCHAR_FIELD_NAME, "测试varchar");
    row.put(FLOAT_FIELD_NAME, ran.nextFloat());
    row.put(DOUBLE_FIELD_NAME, ran.nextDouble());
    row.put(BOOL_FIELD_NAME, ran.nextBoolean());

    // $json
    JSONObject jsonObject = new JSONObject();
    jsonObject.put(INT32_FIELD_NAME, ran.nextInt());
    jsonObject.put(INT64_FIELD_NAME, ran.nextLong());
    jsonObject.put(VARCHAR_FIELD_NAME, "测试varchar");
    jsonObject.put(FLOAT_FIELD_NAME, ran.nextFloat());
    jsonObject.put(DOUBLE_FIELD_NAME, ran.nextDouble());
    jsonObject.put(BOOL_FIELD_NAME, ran.nextBoolean());
    row.put(USER_JSON_FIELD, jsonObject);

    rowsData.add(row);
}

InsertRowsParam param = InsertRowsParam.newBuilder()
        .withCollectionName(COLLECTION_NAME)
