Title:
DATA STORAGE METHOD AND DEVICE, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2019/052209
Kind Code:
A1
Abstract:
The present invention relates to the technical field of information processing, and provides a data storage method and device, and a storage medium. The method comprises: determining, when at least one data record is obtained, bitmaps of tag values in each bitmap index partition, which is comprised by a bitmap index, by means of a preset mapping/protocol model based on the at least one data record to realize storage of the at least one data record into a corresponding bitmap index partition. The bitmap index comprises at least one bitmap, each bitmap corresponds to one of the tag values, and thus a carrier identifier with the tag value can be found by means of the bitmap index based on the tag value, and the efficiency of carrying out data query based on the tag value is improved. In addition, the bitmaps of the tag values in each bitmap index partition can be determined concurrently by means of the preset mapping/protocol model, and the data storage efficiency is improved.
