Data access processing method and device and server

Abstract

The invention provides a processing method and a processing device for data access and a server. The processing method comprises the steps of receiving a data access request including accessed data identifications a in the process of loading all of data in a magnetic disk into an internal memory; inquiring a location table to judge whether the accessed data corresponding to the accessed data identifications are loaded into the internal memory or not if all of data are not completely loaded from the magnetic disk into the internal memory, wherein the location table is used for recording the identifications of the data loaded from the magnetic disk into the internal memory; loading the accessed data corresponding to the accessed data identifications in the magnetic disk into the internal memory and performing access processing to the accessed data in the internal memory if the accessed data are not loaded into the internal memory; and updating the location table according to the accessed data identifications.

Description

technical field [0001] The invention relates to computer technology, in particular to a data access processing method, device and server. Background technique [0002] With the decline of memory integration and cost, large memory systems are becoming more and more common; at the same time, the processing capacity of stand-alone nodes is also constantly improving. At present, the amount of data that needs to be processed by a single machine is also increasing, and the memory database of a single machine can reach the order of 1TB. [0003] figure 1 It is a schematic diagram of the principle of loading data when the stand-alone memory database is started or restarted in the prior art, such as figure 1 As shown, when the stand-alone in-memory database is started or restarted, it needs to wait for all the data to be loaded from the disk into the memory before access processing can be performed. However, limited by the input / output (Input / Output; I / O) access performance of the...
