Problems solved by technology

[0003] (1) Long time for synchronous write operations: During the data migration process, the accumulated write operation data may be a lot, which leads to a relatively long time for subsequent synchronous write operations
[0004] (2) During the route change process, in order to ensure data consistency, data access will be suspended, affecting user experience
[0005] (3) Impact on the traversal operation: During the traversal process, when there is a route change, the traversed data may be incomplete, or the traversal operation may be terminated

Abstract

The present invention provides a peer-to-peer distributed system and a method for adding a node in the peer-to-peer distributed system. According to the method for adding the node in the peer-to-peer distributed system, a source server node parallelly synchronizes write operation to a newly added node when performing data transfer on the newly added node, and therefore, the problem of long consumed time caused by a condition that write operation can be synchronized only after data transfer is completed can be solved, and data access and traverse operation can be better supported in a route change process.

Description

technical field [0001] The invention relates to the field of distributed computing, in particular to a method for adding nodes in a peer-to-peer distributed system and the peer-to-peer distributed system. Background technique [0002] Currently commonly used methods for adding nodes in a peer-to-peer distributed system are as follows: figure 1 As shown in (a)-(d), first migrate the source server node data to the new node, then the source server node synchronizes the write operation to the new node, and finally suspend the client node’s access to the source server node and change the route The source server node and the newly added node cannot provide data access services to the client node until the change is completed. This existing solution is stored in at least the following three problems: [0003] (1) The synchronous write operation takes a long time: During the data migration process, the accumulated write operation data may be large, which leads to a relatively long ...
