Limitations
System resources are not allowed to be added to resource assignments in rules.
You cannot add a dre user, dre_manager, an admin user in the admin group or with admin privileges to member assignments in rules.
Only one exception rule can be executed per request.
Each request is given an initial 2 MB of memory. After the 2 MB is exhausted, then any workload rules with memory limits are applied. This allows normal requests, such as log-in and system requests, to proceed and Studio to continue functioning.
In workload management, the memory limit rule does not restrict a request from consuming ANY memory. It only restricts memory consumption for query engine operators such as DISTINCT, JOIN, GROUP BY, etc.
A user without WLM permission will not be able to view
- the WLM icon on resources.
- rule in lineage panel of a resource.
When a user without WLM permission exports a car file with dependencies, assuming WLM rule exists on a resource, the exported car file will not contain the WLM rule in dependencies.
