Easy to Use

You can edit StreamSQL statements to define the data input, output, and processing. Business logics are implemented quickly, facilitating streaming data analysis.

Fully Hosted

You can check visualized information on running jobs without the need for cluster O&M.

Pay per Use

The service is priced based on the used SPU resources (1 SPU = 1 core + 4 GB memory) and the service duration (by second).

High Throughput, Low Latency

The Dataflow model of Apache Flink is leveraged to achieve a real-time computing framework.

Application Scenarios

IoT

IoT or edge devices upload data to DIS. CS reads data from DIS, analyzes data (including fault detection and counter warning), and makes the analysis result persistent or reports alarms in real time.

Advantages

  • Abundant IoT SQL Functions

    Provides common IoT functions such as area, yaw, and distance detection functions.

  • High Throughput, Low Latency

    Leverages Apache Flink to achieve a complete real-time computing framework.

  • Secure Isolation

    Isolates tenants from each other to ensure data security.
