Problems solved by technology

Therefore, in the application scenario with many write operations, since the distributed system does not have a reasonable deployment of memory partitions, the memory partitions of the system can only be randomly deployed, so the distributed system still needs to perform a large number of cross-network write operations. The delay overhead is large and cannot meet the requirements of practical applications

Abstract

The invention discloses a memory partition deployment method. The memory partition deployment method is used for rationally deploying the memory partition of a distributed system, and reducing the time delay overhead of the distributed system. The memory partition deployment method comprises the steps: determining the hot spot partition in the distributed system within the preset time slot, wherein the distributed system comprises multiple nodes, the memory partition is deployed on the nodes, and the hot spot partition is the memory partition in the distributed system of which the frequency of the visits is arranged in the front rank; determining the frequency of the hot spot partition which is visited by each node; according to the frequency of the hot spot partition which is visited by each node, determining the optimal deployment node of the hot spot partition; informing the optimal deployment node of the hot spot partition to the node currently located by the hot spot partition. The invention further provides a relevant memory partition deployment device.

Description

technical field [0001] The present invention relates to the field of data processing, in particular to a memory partition deployment method and device. Background technique [0002] Distributed memory data grid (IMDG, In-memory Data Grid) is a new type of grid system for memory resource sharing on wide area network. Its main goal is to improve the system performance of memory-intensive applications or IO-intensive applications when physical memory is insufficient. [0003] The distributed memory grid technology uses a consistent hash algorithm to divide the data into blocks and distribute them as much as possible to the memory partitions of all nodes in the distributed system to ensure data balance, but this makes the memory partitions of the distributed system Deployment is relatively random, resulting in distributed systems often requiring cross-network data access. For example, when the processes App1 and App2 on node A access the memory partition Data1 of node B, they ...
