Problems solved by technology

And when the obsolete data block needs to be accessed again, it needs to be read again from the disk, which will lead to performance degradation
In order to improve performance, it is necessary to increase the hit rate of the accessed data in the memory, then it is necessary to increase the memory to load more data blocks, and this will cause the problem of memory expansion

Embodiment Construction

[0046] In order to make the purpose, technical solution and advantages of the application clearer, the embodiments of the application will be described in detail below in conjunction with the accompanying drawings. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined arbitrarily with each other.

[0047] In a typical configuration of the present application, a computing device includes one or more processors (CPUs), input / output interfaces, network interfaces, and memory.

[0048] Memory may include non-permanent storage in computer readable media, in the form of random access memory (RAM) and / or nonvolatile memory such as read only memory (ROM) or flash RAM. Memory is an example of computer readable media.

[0049] Computer-readable media, including both permanent and non-permanent, removable and non-removable media, can be implemented by any method or technology for storage of inf...

Abstract

The invention discloses a data tracking processing method and device, and the method comprises the steps: generating tracking information according to a recorded accessed condition in a tracking processing time period, the tracking information being used for recording the identification information corresponding to an accessed record; selecting at least one snapshot, and determining whether the scanned record exists in the tracking information or not according to the identification information of the scanned record and the generated tracking information; and taking a record corresponding to the scanned identification information existing in the tracking information as tracking data. Through the data processing method provided by the invention, tracking and positioning of the concerned dataare realized.

Description

technical field [0001] This application relates to but not limited to database technology, especially a data tracking processing method and device. Background technique [0002] In a database, data is organized in blocks. When accessing a record, the entire data block where the record is located needs to be loaded into memory, even if only one record in this data block is of interest to the user. In this case, input / output (IO) amplification is virtually caused. [0003] And when the data that the user cares about is distributed in many data blocks, it will cause memory expansion. For example: there are 10,000 pieces of data that the user cares about, but these 10,000 records are distributed in 10,000 different data blocks, so 10,000 data blocks are required to be loaded into the memory. Assuming that 1 data block can store 100 records, then in fact, only 100 data blocks are needed to store the data that users care about, that is, the above 10,000 records. [0004] In ac...
