To enhance the performance of data migration and synchronization using Redis®/Tair as the source, we will be upgrading the architecture of the Data Transmission Service (DTS). This upgrade will introduce functional improvements and changes to the billing model. Please pay attention to the following important details:

• Affected Scenarios: Data Transmission Service (DTS) - Data migration and synchronization links using Redis® or Tair as source
• Effective Date: January 6, 2026 (Singapore Time, GMT+8)
• Changes
  • Functionality Upgrade: Starting from the effective date, the DTS links in the affected scenarios will support the configuration of "number of subtasks," providing better resource flexibility and allowing for easier adjustments to link performance.
  • Billing Changes: Accordingly, the affected DTS links will adopt a new tiered billing model based on the "number of subtasks." The specific costs will vary depending on the number of subtasks, please find details of billing later on the documentations.
• Impact Overview
  • Existing Links: Current DTS links will continue to operate under the original billing model and will not be affected.
  • New Links: Starting from the effective date, any new DTS links of the respective type will follow the new billing model. Note that the pricing under the new model may differ from the current pricing; please refer to the product purchase page for specific details.
  • API Usage: From the effective date, the API calling method for new links will be adjusted to include a parameter related to the "number of subtasks." If you are using code to operate, please be sure to adapt accordingly. You may find detailed guide later in the API documentation.
