As a Jira Administrator you can set an upper limit for issue creating solution.
Meaning, in Jira add-on section you can turn On bulk issues creation and an upper limit after exceeding which issues will be created by bulk create issue solution. In other cases issues will be created in ordinary manner one by one.
It is turned Off by default:
You can easily turn it On and change default value of 100, if you are creating lots of issues using Excel Connector you can consider decreasing this value to increase Jira performance and use bulk create method e.g. when trying to create 20 issues at once.
This feature will be improved over time, as it could heavily increase performance.
It does not require global permission "Bulk Change" (we will change this name in the future)
