Problem Definition

The Sprint field suggestion is calculated based on users' last 5 visited Sprint. If a user has not to visit a minimum of 5 Sprint, the suggestion will be calculated by retrieving ALL SPRINT available to the user and perform some calculation to return number issues associated with each Sprint.

For some Jira configurations, the Sprint field dropdown suggestion may consume a lot of CPU, see JSWSERVER-20445

Suggested Solution

Don't calculate "All sprints" suggestion for those cases.

Fix

It is activated by using this feature flag:
com.atlassian.jira.agile.darkfeature.sprint.picker.allsprints.suggestion.disabled
As soon as this flag is added, "All sprints" suggestion will not be calculated/shown.

Important note

The limitation of this workaround is that users can only search/select Sprints from their own history (the Sprints that they have visited/edited/created).
If the user has not created/edited/visited any sprint and the dark feature is enabled, the drop-down will be empty.
