How are cloud storage and database deletions synchronized in Cloud Development?

In Cloud Development, if you encounter the situation where image files in cloud storage remain preserved after deleting database data, the common practice is to store the corresponding cloud storage file ID along with the data. This allows you to delete the associated cloud storage files simultaneously when deleting the database records.

The following are the processing steps:

  1. Associated field: Ensure that a corresponding cloud storage file ID is stored in the database for each file.
  2. Delete operation: When deleting a database record, use the associated field to locate the file in cloud storage and perform the deletion.
  3. Automated script: If the data volume is large, consider writing an automated script to handle synchronous deletion of database and cloud storage.
  4. Notes: Before performing the delete operation, ensure you have a data backup to prevent data loss.

In this way, you can avoid the hassle of manually deleting files one by one and ensure data consistency between the database and cloud storage.
