Starting with version 4.1.1, Power Scripts Scripts™ is able to cache the results for the expressions used to filter issues, either builtins built-in or user provided. This feature can greatly improve performance as well as degrading degrade it, so use it with extreme care.
Reasons to use itthese features:
- You have saved filters and users perform again and again are performing the same JQL queries over and over again.
- You have plenty of free memory and CPU.
Reasons not to use itthese features:
- You do not have enough free memory.
- CPU is constrained.
- Your users are doing performing ad-hoc queries.
Index is maintained automatically for now, and its parameters are not editable. If enabled, the engine will auto-determine if whether an expression is used frequently , and will trigger a reindex on the respective script. While indexing, the index will not be available, but once completed, it will find issues very-extremely very fast.
Feature is cluster aware, and it should work without problems in clustered environments as well.
To enable it, visit the JQL configuration page, and click on the "Enable Functional Index" button button.
