Modifying the Flow Control Mode

You can choose whether to control the flow. DRS allows you to change the flow control mode after a task is created. Currently, only the following real-time migration types support this function:

  • To the cloud
    • MySQL->MySQL
    • MySQL->GaussDB(for MySQL)
    • MySQL->DDM
    • MySQL schema and logic table -> DDM
    • MongoDB->DDS
    • MongoDB->GeminiDB Mongo
  • From of the cloud
    • MySQL->MySQL
    • DDS->MongoDB

Constraints

  • The flow control mode limits the maximum traffic speed in seconds. The actual statistical value may be lower than the flow rate because the statistical value may decrease due to network fluctuation.
  • The flow control mode takes effect only in the full migration phase.
  • After the traffic rate is modified in the incremental migration phase, the modification takes effect when the task enters the full migration phase again.

Prerequisites

  • You have logged in to the DRS console.
  • A migration task has been created.
