Abstract
A technique for reducing recovery time in a computing apparatus includes: storing data in a key-value store residing in a persistent memory, the key-value store including a plurality of persistent nodes including key-value pairs, the key-value pairs of the persistent nodes being unsorted; caching selected persistent nodes in a volatile memory, the key-value pairs of the cached nodes being sorted, the caching including instantiating a dual pointer for each cached node, the dual pointer including a volatile pointer to a child node of the cached node and a persistent pointer to the child node of the corresponding persistent node in the key-value store; and rebuilding the cache of selected nodes upon demand using the dual pointers in the event of recovery.
