The UI Bookmark
mainly stores User-Specific Configurations, Saves States or sessions, Bookmarks or favorite items, custom filters, or searches.
When you truncate data from this ui_bookmark table it restores the default settings.
As you are concerned about your users, you can safely truncate the table using the criteria below.
Identify your namespace (there is a column namespace in ui_bookmark, for eg. customer_listing
)
Identify the user in the field user_id
Now you have a namespace and user_id
, add a condition in your delete query so that it deletes data for the user for which you are facing the issue.
For example,
DELETE FROM ui_bookmark WHERE namespace = 'customer_listing' AND user_id = 2;
Thanks!
