@DevC16698431 The alert indicating 90% storage usage in the CDH application suggests that the storage might still be filled even after removing data from tables. In addition to truncating tables, you should check for other potential storage issues such as logs or temporary files taking up space, large indexes, or backup files that may not have been removed. You can look into the file system to see if there are large files in directories like the logs folder, which might need to be cleared. Also, verify if there are any database caches or session data that need cleaning. If the problem persists, consider checking the database’s internal storage management or consult with your infrastructure team for further insights into the issue.
