Dictionary tree construction method and device, equipment and storage medium

The invention discloses a dictionary tree construction method and device, equipment and a storage medium. The method comprises the following steps: acquiring an external identifier of point data and an internal identifier of the point data in graph data; and according to the external identifier of the point data and the internal identifier of the point data, constructing the dictionary tree. Through the technical scheme of the invention, the mapping relationship between the internal identifier and the external identifier of the point data can be quickly obtained based on the constructed dictionary tree; therefore, the problems of low efficiency, long time consumption and large disk or memory consumption when the graph data is put into the database or the memory are solved, and the performance during data import is improved. 本发明公开了一种字典树构建方法、装置、设备及存储介质。该方法包括：获取图数据中的点数据的外部标识和点数据的内部标识；根据所述点数据的外部标识和所述点数据的内部标识构建字典树，通过本发明的技术方案，能够基于构建的字典树快速获取点数据的内部标识和外部标识的映射关系，从而解决图数据入库或者入内存时效率低、用时长以及磁盘或内存消耗大的问题，进而提升数据导入时的性能。
