To improve the initial performance of your Backoffice application, you can use the defined bean backofficeWarmUpTypeFacadeCaches. This bean is responsible for prefilling caches in the TypeFacade. You can configure which types should be prefetched introducing property typeNames.

You can disable this functionality by setting up the parameter fill.typefacade.cache.on.startup to "false" in your "local.properties" file.

The property afterInitializationEndBackofficeListener referes to the bean afterInitializationEndBackofficeListener defined in the "backoffice-spring.xml" file. The purpose of the bean is to listen to the system event AfterInitializationEndEvent and allow the bean warmUpTypeFacadeCaches to update its cache after the system initialization.

Please refer to the official documentation for more details on Backoffice extension customization.
