Remote heap management method and remote heap management system

Abstract

The invention discloses a remote heap management method and a remote heap management system, which are applied to a client, and the remote heap management method comprises the following steps: dividing a log area from a local storage space; receiving a write-in request of object data; writing the object data into a log area; whether the object data is updated data or not is judged, if yes, a space corresponding to original object data in a storage section of a remote heap space is marked as a free area, the object data is placed at a new storage position, the remote heap space comprises multiple sections, and the multiple sections comprise the storage section and the free section; otherwise, judging whether the storage space of the log area is equal to the rated space or not; transmitting all object data in the log area to a current corresponding idle section of the log area, emptying the log area, marking the current corresponding idle section as a storage section, selecting a next idle section as a current corresponding section of the log area, and then re-receiving a write-in request of the object data; otherwise, re-receiving the write-in request of the object data.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a remote heap management method and a remote heap management system. Background technique [0002] In a cloud computing environment, memory resources are the most competitive resources. In the server clusters of Google and Alibaba, the average memory utilization is 60%, and there are huge differences in the memory utilization of different nodes, in contrast, the average CPU utilization is only 40%. In addition, memory resources are the most difficult to scale resources in a cloud computing environment. Because the application can only use the local memory, once the local memory is exhausted, some applications must be forcibly closed to release memory resources. According to statistics, in Google's data centers, 790,000 applications were forcibly closed due to insufficient memory within a month. Due to the difference in memory utilization of each node in the cluster, there ar...
