林业资源数据集群的快速索引设计

Abstract

Abstract:

This paper describes the design of a fast index for distributed storage of forestry resource data. According to the load data request of a large number of independent data nodes to reduce the mutual exclusion during data access, parallel access was realized for distributed storage of spatial and attributive data. Based on the common application server cluster, this fast index can be used by making the minor modifications of data access process so as to improve the performance of statistics and update of the whole data cluster with low cost.

Key words: forestry resource, cluster data storage, multiple database storage, parallel index
