A specialized in-memory database health check process is utilized to resolve dependencies in a resource indicating requirements for an instance of an in-memory database. Specifically, when an instance of an in-memory database is created in response to a request, a list of one or more component handlers are obtained. These component handlers are modular functions, separate from each other but potentially dependent on one or more other component handlers, and act to validate various requirements listed in a resource for the request. Each of the component handlers are executed individually during execution of a Reconcile function. To the extent that the execution of any component handlers in the list is unsuccessful, the Reconcile function is rerun for another iteration. These iterations continue until all component handlers report back as successful. Instance creation is then considered successful and the instance of the in-memory database can be utilized by users.

Executing and re-executing a list of component handlers defined for a resource in response to detecting a creation, deletion, or modification of the resource

Systems, methods, and software can be used to select a boot loader. In some aspects, a primary boot loader on an electronic device invokes a boot selector stored on a permanent memory storage on the electronic device. The boot selector selects a secondary boot loader stored on the electronic device. The selected secondary boot loader is executed to boot the electronic device.
