Figure 1 ClickHouse application development process

**Table 1** Application development process
Phase	Description	Reference
Preparing the development environment	ClickHouse applications can be developed in a variety of languages. You are advised to use the Java language and IntelliJ IDEA tool, and complete initial configurations of JDK and Maven.	Preparing the Development Environment
Preparing the configuration files for connecting to the cluster	During the development or a test run of the program, you need to use cluster configuration files to connect to an MRS cluster. The configuration files usually contain the cluster information file and user files used for security authentication. You can obtain the required information from the created MRS cluster. Nodes used for program debugging or running must be able to communicate with the nodes within the MRS cluster, and the hosts domain name must be configured.	Preparing the configuration files for connecting to the cluster
Configuring and importing sample projects	ClickHouse provides a range of sample projects for different scenarios. You can obtain a sample project and import it to the local development environment.	Configuring and Importing a Sample Project
Writing program code for a service scenario	Sample projects are provided to help you quickly understand APIs of ClickHouse components.	Application Development
Compiling and running applications	Compile and run the program. You can debug and run the program in the local Windows development environment, or compile the program into a JAR package and submit it to a Linux node.	Commissioning Applications on Windows Commissioning Applications on Linux
