Hi Teams,

As on date, the bulk delete issue feature of Jira is a single threaded operation and is very slow at times when there are needs to delete millions of issues to support migrations.

As per documentation: https://support.atlassian.com/jira/kb/bulk-mass-delete-issues-in-jira/, we understand that it is intended by design to avoid performance issues.

We would like to have a configurable option, or a dark feature to make this operation multi-threaded when we have use-cases of deleting millions of issues. 

Thank you.
