-## Optimization of Caches
-
-** Cache pruning is an experimental feature. Might a subject of change or even removal in the future. **
-
-Operators using informers will initially cache the data for all known resources when starting up 
-so that access to resources can be performed quickly. Consequently, the memory required for the 
-operator to run and startup time will both increase quite dramatically when dealing with large
-clusters with numerous resources. 
-
-It is thus possible to configure the operator to cache only pruned versions of the resources to 
-alleviate the memory usage of the primary and secondary caches. This setup, however, has 
-implications on how reconcilers deal with resources since they will only work with partial 
-objects. As a consequence, resources need to be updated using PATCH operations only, sending 
-only required changes. 
-
-To see how to use, and how to handle related caveats regarding how to deal with pruned objects 
-that leverage

-and associates reconciler.

-Pruned caches are currently not supported with the Dependent Resources feature.
