Abstract

The invention discloses a memory cache data system and a data indexing method, and relates to the technical field of computers. One specific embodiment of the system comprises the following steps: storing original data of a plurality of targets in a preset data container in a memory cache; wherein the original data comprises data of at least one index dimension; wherein the original data of each target in the plurality of targets is used as an element of the data container, and each target has a unique subscript of the data container; the system further comprises bitmap data corresponding to each sub-dimension of the index dimension and used for indexing the original data; wherein each bitmap data comprises values of the plurality of targets arranged according to a preset sequence based onthe subscripts in the sub-dimensions corresponding to the bitmap data. According to the embodiment, the multi-dimensional data of targets can be stored, the Bitmap algorithm is used for constructingthe index structure, and multi-dimensional efficient indexing of the memory cache data is achieved.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a memory cache data system and a data index method. Background technique [0002] In existing caching technologies, data is generally stored based on a hash table structure, and when data is indexed, a corresponding Value (value) is searched according to a Key (key) in the hash table. In this data structure, only one-to-one indexing of Key and Value can be performed, and it does not have the ability to index based on multiple data dimensions, and cannot support high-dimensional data structures and complex business requirements. Contents of the invention [0003] In view of this, an embodiment of the present invention provides a memory cache data system and a data indexing method, which can store multi-dimensional data of a target and use the Bitmap algorithm to build an index structure, so as to realize multi-dimensional and efficient indexing of memory cache data. [0004] ...
