Summary:

Certain project/instance level operations will trigger the method forceCreateSnapshot() which causes Jira to generate an index snapshot outside of the scheduled job parameter/s.

Known operations that trigger the forceCreateSnapshot() method are Project Re-index and Project Archive. Project re-index can be triggered manually via the following actions:

• Project Settings > Project re-index (manual)
• SLA recalculation (JSM)
• Plugin/app operations (especially those that recalculate SLAs or update many issues)

Suggestion:

The scope of this request is to allow Jira Administrators to disable forceCreateSnapshot() so that snapshots are only generated at the scheduled time each day. In scenarios where resource constraints can occur due to the added pressure from snapshot generation it is necessary to mediate potential HEAP/CPU exhaustion from such operations.
