To enhance the user experience, we will be optimizing the backup download functionality for certain ApsaraDB products. This optimization will significantly improve the download speed of the Advanced Download feature, delivering a smoother and more efficient user experience. Please take note of the following key details:

• Affected Products: ApsaraDB RDS for MySQL, PolarDB for MySQL
• Affected Feature: Advanced Download
• Effective Date: August 15, 2025 (Singapore Time, GMT+8)
• Optimization Details: This optimization will involve upgrading our file processing algorithms, resulting in a notable increase in download speed for the Advanced Download feature.
• Impact & Recommendations:
  • API Calls: Configuration and workflows remain unchanged. If you use APIs to execute periodic Advanced Download tasks, no modifications to existing API calls are required.
  • File Differences: The number of downloaded files and the decompression method may differ. If your workflows involve automated post-download processing, please test and adapt your procedures based on the latest documentation after the upgrade takes effect.
