Embodiment Construction

[0028] figure 1 is a schematic structural diagram of an in-memory database management device according to an embodiment of the present invention. Such as figure 1 As shown, the memory database management device disclosed in the present invention includes a data storage unit 1 , a data query unit 2 and a memory pool management unit 3 . Wherein, the data storage unit 1 is configured to receive a data record storage request from an external application and store the data records to be stored contained in the data record storage request in a hash structure in the memory pool management unit 2. in the allocated memory space. The data query unit 2 is configured to receive a data record query request from an external application, execute a query operation based on the data record query request, and then send the query result back to the external application. The memory pool management unit 3 is configured to allocate memory space according to the memory allocation instruction from...

Abstract

The invention provides a memory database management device. The device comprises a data storage unit, a data querying unit and a memory pool management unit, wherein the memory pool management unit is used for distributing memory space according to memory allocation instruction from the data storage unit and transferring the address of the distributed memory space back to the data storage unit; the distributed small-sized memory space comprises the following hierarchical structure: memory clusters, memory barrels and memory blocks, each memory cluster comprises a plurality of memory barrels; each memory barrel comprises a plurality of memory blocks. The memory database management device is low in maintenance cost, is customized and expanded and can effectively improve the data storage and query efficiency.

Description

technical field [0001] The present invention relates to a database management device, more particularly, to an internal memory database management device. Background technique [0002] At present, with the increasing demand for information and data processing and the increasing variety of business types in different fields, the use of memory-based database management systems (that is, database management systems that use computer main memory as a data storage carrier, because they do not use disks, so It saves the I / O time overhead for disk, which can significantly improve data storage and query efficiency) is becoming more and more important. [0003] The existing commercially available technical solutions have the following problems: high maintenance cost and difficulty in individual customization and expansion. [0004] Therefore, there is a need to provide an in-memory database management device that has low maintenance cost, can be customized and expanded, and can sign...
