Disk Usage Increases After Data Fails to Be Imported Using GDS

Updated on 2024-03-08 GMT+08:00

Symptom

A user uses GDS to import data but fails, triggering data import again. After data is imported, the user checks the disk space and finds that newly occupied disk space is much greater than the imported data volume.

Cause Analysis

After data fails to be imported, the occupied disk space is not released.

Solution

  1. Check the logs of GDS import jobs to see whether any execution failure occurs.
  2. Clear the related table or partition.
