Cache management method and device, medium and equipment

Abstract

The invention belongs to the technical field of computers, and particularly relates to a cache management method and device, a medium and equipment. The method comprises the following steps: if object data stored in a cache region is called, creating a first reference pointer for pointing to the object data according to the object data; storing the first reference pointer into a first reference table, and adding a first numerical value to a preset parameter of the object data; releasing the first reference pointers according to the number of the first reference pointers in the first reference table and the storage sequence, and subtracting the first numerical value from the preset parameter of the object data of the released first reference pointers; and when the preset parameter of the object data is smaller than or equal to a first preset threshold value, releasing the object data from the cache region. According to the technical scheme provided by the embodiment of the invention, the system memory occupied by the application can be reduced under the condition of ensuring the operation performance of the application, and the optimization of cache management is realized.

Description

technical field [0001] The present application belongs to the field of computer technology, and specifically relates to a cache management method, apparatus, medium and device. Background technique [0002] In recent years, the in-memory data required by computing systems has continued to grow, so it is necessary to provide larger memory space for in-memory data computing technology. Currently, in-memory data processing frameworks are widely used in applications such as machine learning, graph computing, and stream processing. Random Access Memory (RAM) is used as memory. Since RAM accesses data several orders of magnitude faster than accessing data from the hard disk and the network, the memory data processing framework can also execute applications faster. a substantial increase. However, the high price of RAM results in limited memory resources, and only part of the data can be cached in memory. Based on this, memory cache resources need to be managed. [0003] Under n...

However, the high price of RAM leads to limited memory resources, and only part of the data can be cached in memory. Based on this, memory cache resources need to be managed

[0003] In general, the more cached data, the more obvious the improvement of system application performance, but due to the limitation of fast device space such as memory, it is impossible to cache unlimited data

For example, in the Linux operating system, when the physical memory is exhausted, the swap partition will be used. Since the performance of the swap partition is not as good as that of the memory, swapping the memory data to the swap partition will seriously reduce the performance of the application system.
