Functions

Key Modules

DIS consists of the following four functional modules:

• Service control
  • Creates, deletes, and configures DIS streams; synchronizes user information to the data plane.
  • Allocates resources and automatically deploys DIS on the data plane.
• Data processing
  • Receives user requests, and receives and stores authenticated data.
  • Receives data read requests and returns the requested data to authorized users.
  • Removes old data from DIS streams according to data aging policies.
  • Stores user data into OBS, MRS, DWS, or DLI.
• Service maintenance
  • Installs and upgrades DIS.
  • Performs configuration, preventive maintenance, monitoring, and log collection and analysis for DIS.
  • Processes service orders.
• User SDK
  • Provides Java APIs for users to push and pull data.
  • Encrypts data.

Key Capabilities

• Scalable: A DIS stream can seamlessly scale its data throughput from megabytes to terabytes per hour, and from thousands to millions of PUT records per second.
• Easy to use: You can create a DIS stream within seconds. It is easy to put data into a stream, and build a data processing application.
• Low cost: DIS has no upfront cost and you only pay for the resources you use.
• Parallel processing: DIS allows you to have multiple DIS applications processing the same stream concurrently.
• Secure and reliable: DIS can retain data for 24 to 72 hours to prevent data loss in case of application faults, individual machine faults, or facility faults.
