IoTDB Sample Project

To obtain an MRS sample project, visit https://github.com/huaweicloud/huaweicloud-mrs-example and switch to the branch that matches the MRS cluster version. Download the package to the local PC and decompress it to obtain the sample project of each component.

MRS provides the following IoTDB sample projects.

**Table 1** IoTDB sample projects
Sample Project Location	Description
iotdb-examples/iotdb-flink-example	Program for using Flink to access IoTDB data, including FlinkIoTDBSink and FlinkIoTDBSource data. FlinkIoTDBSink can use Flink jobs to write time series data to IoTDB. FlinkIoTDBSource reads time series data from IoTDB through Flink jobs and prints the data. For details, see IoTDB Flink.
iotdb-examples/iotdb-jdbc-example	Java sample program for IoTDB JDBC to process data This example demonstrates how to use JDBC APIs to connect to IoTDB and run IoTDB SQL statements. For details, see IoTDB JDBC.
iotdb-examples/iotdb-kafka-example	Sample program for accessing IoTDB data through Kafka This program demonstrates how to send time series data to Kafka and then use multiple threads to write the data to IoTDB. For details, see IoTDB Kafka.
iotdb-examples/iotdb-session-example	Java sample program for IoTDB Session to process data This example demonstrates how to use Session to connect to IoTDB and run IoTDB SQL statements. For details, see IoTDB Session.
iotdb-examples/iotdb-udf-exmaple	This sample program describes how to implement a simple IoTDB user-defined function (UDF). For details, see IoTDB UDF Program.
