Abstract

The invention discloses a bitmap generation method and device, equipment and a storage medium. The method includes the steps of determining target data to be subject to bit transformation; calling a preset hash algorithm to calculate a bit id of an integer type corresponding to the target data; and storing the bit id in the bitmap. The scheme provided by the embodiment of the invention directly calls the hash algorithm with low collision rate to calculate the bit id when determining the target data requiring bit transformation, thus greatly improving the calculation efficiency of the bit id. Besides, the complexity of the system is reduced because the distributed int id generation engine does not need to be set.

Description

technical field [0001] The present invention relates to the field of data processing, in particular to a bitmap (bitmap) generating method, device, equipment and storage medium. Background technique [0002] User package extraction is usually required in data analysis, and bitmap technology is often used for user package extraction. Bitmap calculation requires the system to provide a standard int (integer type) element id, namely bitid, for data assembly. For example: in the business system, the data of varchar (variable length) string type is used as the unique identifier of 'user'. In order to save 'user' as an 'element' in the bitmap into the bitmap, the varchar value identifier of the element needs to be converted into A numeric identifier of type int. In order to meet such needs, for non-int primary key data, it is necessary to provide a distributed int id generator to generate the bit id available to the bitmap, which increases the complexity of the system and reduce...
