Abstract
In certain embodiments, a method includes starting an application as a first process within a user space of an operating system. The application instantiates a key-value store and a file system associated with the operating system. The method also includes managing, by a block device service running within the user space, one or more first data blocks of a persistent storage allocated to the key value store and one or more second data blocks of the persistent storage allocated to the file system. In addition, the method includes receiving, by a kernel of the operating system, a system call request comprising an access request generated by the key-value store or the file system. The method further includes granting, by the block device service, and in response to the access request, the key value store or the file system access to the one or more first or second data blocks.
