We are finding that users are abusing the 'Excel (All fields)' export and downloading hundreds of unnecessary fields which for large queries can slow and even crash JIRA.
We have over 1000 custom fields so depending what's in context for the filter there could be say 400 fields in the spreadsheet which will mostly not be relevant to the user. If the All fields option were removed it would force users to specify the fields they want rather than taking the easy option and then deleting the unwanted columns in Excel.
What is the best way to disable the 'Excel (All fields)' feature? Is there a flag or permission in JIRA or would we need to mess with templates?
NB some of our users are smart enough to figure out the URL so just removing the option from the list probably won't stop them!
