Abstract: A first plurality of block identifiers is sorted based, at least in part, on a measure of spatial locality. A second plurality of block identifiers is sorted based, at least in part, on the measure of spatial locality. At least the first plurality of block identifiers and the second plurality of block identifiers are incrementally merged into a third plurality of block identifiers based, at least in part, on the measure of spatial locality. A block of data corresponding to metadata associated with a plurality of block identifiers of the third plurality of block identifiers is updated.

Abstract: Methods, non-transitory computer readable media, and computing devices that accelerate data access requests. With this technology, a hierarchy of a objects is inserted into a location database. Each of at least a subset of the objects comprises a physical storage location for data stored in a filesystem. One or more of the objects includes an object version number and a parent version number of a parent one of the objects. A determination is made when an invalidation event has occurred in the filesystem. The invalidation event is associated with one of the objects. The object version number for the one of the objects is modified to invalidate one or more of the subset of the objects, when the determining indicates that the invalidation event has occurred in the filesystem.
