Development Process
This document describes how to develop CQL applications based on Java APIs.
Figure 1 and Table 1 describe the phases in the development process.
| Phase | Description | Reference Document |
|---|---|---|
| Understand the basic concepts. | Before application development, learn basic concepts of CQL and understand the scenario requirements. | |
| Prepare the development and operating environment. | Use the IntelliJ IDEA tool to call Java APIs to develop CQL applications. The CQL operating environment is a Storm client. Install and configure the client according to the guide. | |
| Prepare projects. | CQL provides sample projects for different scenarios. You can import a sample project to learn applications. | |
| Develop projects based on scenarios. | Sample projects are provided, including projects about how to generate random numbers and how to collect statistics by condition. | |
| Compile and run applications. | Storm sample applications are running in the Linux OS. IntelliJ IDEA code needs to be packaged into a JAR package. | |
| View application running results. | Application running results are exported to a path you specify. You can also view the application running status on the UI. |
