Memory allocation method and device, electronic device and storage medium

Abstract

The present application provides a memory allocation method and device, an electronic device, and a storage medium, wherein the method includes: receiving a memory application message sent by a first thread, wherein the first thread is a thread corresponding to a target application, and the memory application The message is used to apply for the memory space of the target memory size; in response to the memory application message, the target memory block corresponding to the target thread ID of the first thread is determined from multiple memory blocks, wherein the multiple memory blocks are allocated for the target application Memory block, multiple memory blocks allow parallel locking to apply for memory; in the case of finding the first memory space whose memory size is greater than or equal to the target memory size from the free memory space of the target memory block, allocate the first memory space to first thread. The present application solves the problem that the memory allocation method in the related art tends to cause low memory allocation efficiency caused by locking and serialization when multiple threads concurrently apply for memory.

Description

technical field [0001] The present application relates to the field of data processing, and in particular to a memory allocation method and device, electronic equipment and storage media. Background technique [0002] At present, in the business logic (for example, the use of memory cache) of databases such as MySQL (a relational database management system), the memory space used for querying data and updating data is passed through malloc (memoryallocation, which refers to dynamic memory allocation) function) allocation, that is, all memory space is completed through dynamic application. [0003] Most of the above business logic uses temporary memory. After a transaction or a connection is completed, all the dynamically applied memory space will be released. During a transaction, there are a large number of memory applications to be released. lead to massive memory fragmentation. [0004] For the allocation method of the above memory space, the memory application is too f...

AI Technical Summary

Problems solved by technology

[0005] The present application provides a memory allocation method and device, electronic equipment and a storage medium, so as to at least solve the problem of low memory allocation efficiency caused by locking and serialization in the memory allocation method in the related art when multiple threads concurrently apply for memory.
