CN111177611A - Method for multiplexing cache - Google Patents

Abstract

The invention discloses a method for multiplexing cache, firstly, storing the operation result of a method needing to be cached in a cache; recording which data table information can be read by the method; when a certain data sheet is changed, the method using the data sheet is triggered to expire; thus, part of the buffered data is retained. The multiplexing caching method used by the invention can improve the performance of the whole system under the condition of small-amplitude content modification.

Description

Method for multiplexing cache

Technical Field

The invention belongs to the technical field of internet, and particularly relates to a multiplexing caching method.

Background

In an actually operating business system, in order to improve data reading performance, a method called cache is adopted, when data writing operation is performed, all caches are invalidated, and therefore, when the next operation is performed, a large amount of data reading and calculation operations need to be performed to recover the cache again. However, in this process, a large part of data is actually not required to be read and calculated again, so that a large amount of resources are wasted.

Disclosure of Invention

In order to overcome the defects of the prior art, the invention provides a method for multiplexing a cache.

The invention is realized by the following technical scheme:

a method for multiplexing a buffer, comprising the steps of:

(1) firstly, storing a method operation result needing caching in a cache;

(2) then recording which data table information can be read by the method;

(3) when a certain data sheet is changed, the method using the data sheet is triggered to expire;

(4) the last part of the buffered data is preserved.

The invention has the beneficial effects that: the multiplexing caching method used by the invention can improve the performance of the whole system under the condition of small-amplitude content modification.

Drawings

A more complete understanding of the present invention, and the attendant advantages and features thereof, will be more readily understood by reference to the following detailed description when considered in conjunction with the accompanying drawings wherein:

FIG. 1 is a schematic diagram of a method invocation of the present invention;

FIG. 2 is a schematic diagram of page effect according to the present invention.

Detailed Description

The present invention will be described in detail with reference to specific embodiments, which are illustrative of the invention and are not to be construed as limiting the invention.

A method for multiplexing a buffer, comprising the steps of:

(1) firstly, storing a method operation result needing caching in a cache;

(2) then recording which data table information can be read by the method;

(3) when a certain data sheet is changed, the method using the data sheet is triggered to expire;

(4) the last part of the buffered data is preserved.

As shown in FIG. 1, the Content of the entire page comes from the Content part and the pendant widget1 and widget2 parts, and the Content part comes from the func1 and func2 methods of the Contentclass; widget1 content comes from the func1 and func2 methods of Widget Class 1; the content of Widget2 comes from the func1 and func2 methods of Widget class 2. These contents together make up the entire page.

As shown in fig. 2, it is assumed that in fig. 2, the data included in the areas 1 to 5 are from different data tables, and when an operator maintains the data of the area 2, the entire page cache is emptied according to the history state, and all caches need to be regenerated, but after using the present invention, only the corresponding data needs to be read from the data table in which the content of the area 2 is located, and the content of the areas 1 and 3 to 5 needs to be directly read from the previously recorded caches.

In summary, the multiplexing caching method used in the present invention can improve the performance of the whole system in the context of small-amplitude content modification.

Claims (1)

1. A method for multiplexing a buffer, comprising the steps of:

(1) firstly, storing a method operation result needing caching in a cache;

(2) then recording which data table information can be read by the method;

(3) when a certain data sheet is changed, the method using the data sheet is triggered to expire;

(4) the last part of the buffered data is preserved.
