Problems solved by technology

But adopting the above-mentioned method of writing data cannot simultaneously take into account the speed of writing data from NVM to the log area of ​​the hard disk and the speed of sorting out the written data in the log area of ​​the hard disk
[0005] Specifically, if you want to ensure the speed of writing data to the log area of ​​the hard disk, you may sacrifice the speed of data sorting; if you want to ensure the speed of data sorting, you may sacrifice the speed of writing data to the log area of ​​the hard disk. The number of read and write operations per second (Input / Output Operations Per Second, IOPS) during processing is poor

Embodiment 1

[0055] An embodiment of the present invention provides a data processing method, such as figure 1 shown, including:

[0056] S101. If the used log space of the log area of ​​the first hard disk group is higher than the preset threshold, the data processing device writes the first data read from the internal memory and the characteristic value of the first data into the log of the second hard disk group area, and suspend the collation of the data written in the log area of ​​the second hard disk group to the first data area.

[0057] Wherein, the data written in the log area of ​​the second hard disk group includes the first data.

[0058] It should be noted that the data processing device in the embodiment of the present invention may be a data control module or a data processing module in the database, which is used to control writing and reading of data in the database. For example, the data control module may be a central processing unit (Central Processing Unit, CPU) of ...

Embodiment 2

[0084] An embodiment of the present invention provides a data processing method, taking two hard disk groups (the data areas of the first hard disk group and the second hard disk group) respectively performing log writing and data sorting as an example, in this embodiment, as Figure 6 As shown, the first hard disk group includes the log area and the data area, and the second hard disk group includes the log area and the data area; the first data area is the data area of ​​the second hard disk group, and the second data area is the data area of ​​the first hard disk group ;Such as figure 2 As shown, the method of this embodiment may include:

[0085] S201. A process in which the data processing device writes data to be written into a memory.

[0086] It should be noted that the memory in this embodiment of the present invention may include: a first memory unit and a second memory unit. Wherein, for the specific description of the first memory unit and the second memory unit...

Embodiment 3

[0167] The embodiment of the present invention provides a data processing method. Two hard disk groups (the first hard disk group and the second hard disk group) are used for log writing and data arrangement respectively, and the other hard disk group (the third The data obtained by hard disk group arrangement is taken as an example. In the embodiment of the present invention, such as Figure 7 As shown, the first hard disk group only includes the log area, and the second hard disk group only includes the log area; the first data area and the second data area are both data areas of the third hard disk group; image 3 As shown, the method of this embodiment may include:

[0168] S301. A process in which the data processing device writes data to be written into a memory.

[0169] It should be noted that the memory in this embodiment of the present invention may include: a first memory unit (such as NVM) and a second memory unit (such as DRAM). Wherein, for the specific descrip...

Abstract

The present invention relates to the technical field of storage. A data processing method and device, the data processing method comprising: if the log space usage in the log region of a first hard disk pack exceeds a preset threshold, then writing into the log region of a second hard disk pack a first data and the characteristic value of the first data read from the memory, and stopping the transferring of the organized data having been written into the log region of the second hard disk pack to a first data region; and according to the characteristic value of the data having been written into the log region of the first hard disk pack, organizing the data having been written into the log region of the first hard disk pack and transferring the data to a second data region. The method and device can improve both data writing speed and data organization speed, and enhance the IOPS performance of data processing, further achieving quick data persistence.

Description

technical field [0001] The invention relates to the field of storage technology, in particular to a data processing method and device. Background technique [0002] With the rapid development of processor technology, existing storage systems are not enough to match the rapidly developed processor system, resulting in increasingly prominent bottlenecks in storage technology. Among them, the bottleneck phenomenon of the development of storage technology is mainly reflected in two aspects: the writing and reading speed of data in the storage system is low. [0003] In the prior art, to increase the writing and reading speed of data in the storage system, data writing and reading can be performed in an all-memory manner. Specifically, after receiving the data write command, write the data to be written into the dynamic random access memory (Dynamic Random Access Memory, DRAM), so that after receiving the data read command, it can be directly read from the DRAM Read the corresp...
