Abstract
A persistent data structure store may include an architecture that utilizes dual representations of data hosted in persistent storage coupled with a faster non-persistent cache residing in volatile memory. The persistent data structure store may maintain, in a non-volatile persistent memory, a byte-addressable persistent copy of a data structure storing multiple data values. The persistent data structure store may also maintain a copy of at least some of the data values in a cache copy of the data structure in a volatile memory. When updating values in the data structure, the targeted data value may be updated in the cache copy of the data structure and a log entry specifying the data update may be added to a cross-referencing data operations log from which the data operation will be subsequently applied to the persistent copy of the data structure.
