1. Project Overview

Streamis is a streaming application development and management system jointly developed by WeBank and Tianyi Cloud、Xianweng Technology and Samoyed Cloud .

Leveraging the framework capabilities of DataSphere Studio and its underlying integration with Linkis's Flink engine, it enables users to develop, debug, publish, and manage streaming applications in production environments at a low cost.

Future plans also include a workflow-based graphical drag-and-drop development experience, where streaming applications will be connected into a streaming workflow through Source, Dimension, Transform, Sink, and Visualis nodes. This will enable users to develop, debug, and publish streaming applications with a lower learning curve.

4. Feature Overview

Key Features

Built on DSS and Linkis, this platform delivers a leading streaming application development and management system.

Using Flink as the underlying computing engine, it adopts an architecture that separates the Development Center from the Production Center. Development permissions are completely isolated from publishing permissions, and development environments are isolated from production environments, ensuring high stability and security for business applications.

The application development layer is seamlessly integrated with DSS's data application development workflow, providing an extremely simple user experience.

The application execution layer integrates Linkis computing middleware to provide financial-grade streaming application management capabilities, including high concurrency, high availability, multi-tenant isolation, and resource management.
