Embodiment Construction

[0030] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0031] In the embodiment of the present invention, configure cached nodes and corresponding memory slices, store data index information and pointers to corresponding memory slices in nodes, store data in memory slices, and The memory slices perform various data cache processing operations, such as inserting records, reading records, or deleting records.

[0032] FIG. 2 shows the cache structure provided by the embodiment of the present invention, including two areas, a node area and a memory fragment (Chunk) area. The memory slice area is a shared memory area allocated in memory. The shared memory...

Abstract

The present invention, which applies to the data cache field, provides a data cache process method, method and device. The method includes the following steps: configure a node in a cache and a corresponding memory slice; the node is used for storing the index information of the data and pointing to a pointer of the corresponding memory slice which is used to store the data written into the cache; according to the configured node and corresponding memory slice, cache the data. The present invention has a low demand on a data size, a good generality and requires no prior knowledge of single storage data size and distribution, thus not only enhancing generality of the cache, but also reducing memory waste as well as improving memory usage rate.

Description

technical field [0001] The invention belongs to the field of data cache, and in particular relates to a data cache processing method, system and data cache device. Background technique [0002] In computer and Internet applications, in order to increase the user's access speed and reduce the pressure on the back-end server, the front-end of slow systems or devices such as databases and disks generally adopts cache (Cache) technology, using memory and other fast access The device stores data frequently accessed by users. Because the access speed of memory is much faster than that of disk, it can not only reduce the pressure on back-end devices, but also respond to user requests in a timely manner. [0003] Various data types can be stored in the cache, such as user attribute data, picture data, and various files that the user needs to save. FIG. 1 shows the structure of an existing cache, including a header structure, a hash (Hash) bucket, and multiple nodes (Node). Among t...
