Embodiment Construction
[0035] Below according to accompanying drawing of description, in conjunction with specific embodiment, the present invention is further described:
[0036] A high-efficiency indexing method for massive data in cloud computing. The method uses logs to record the split history of nodes on the basis of distributed B-trees, and efficiently and concurrently accesses distributed B-trees based on the split history of nodes, which effectively improves cloud computing. Massive, distributed data access and indexing efficiency in the environment.
[0037] Described method specific content is as follows:
[0038] Each server has a B-tree node split log, which is used to record the split history of all B-tree nodes distributed in the server;
[0039] The splitting history is a record file sorted in chronological order. Its structure is shown in Figure 1. Each splitting of a node is recorded in the log as a record;
[0040]The record structure in the log is: , where LowValue and UpValue ...
