Embodiment Construction

[0062] For ease of understanding, a brief introduction is first made to relevant terms involved in the embodiments of the present invention.

[0063] Tags are a way of organizing content, which is used to characterize a certain characteristic of data and then help people describe and classify content. For example, common tags include gender, education, occupation, color, and so on. Optionally, the labels are artificially specified.

[0064] One possible implementation, the tags can include two types of enumeration tags and Boolean tags. An enumeration tag refers to a tag that includes multiple enumeration values. For example, education includes college, undergraduate, graduate, doctor, etc., and gender includes male or female; Boolean tags are only used to indicate whether the tag is available, such as , Whether you have a house, whether you have taken drugs, whether you have a criminal record, etc.

[0065] When the label is an enumeration label, the label value of the lab...

Abstract

The application discloses a data storage method and data storage devices and a storage medium, and belongs to the technical field of information processing. The method includes when at least one datarecord is acquired, determining bitmaps of label values in each bitmap index partition, which is included by an bitmap index, through a preset mapping / reducing model on the basis of 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 includes at least one bitmap, each bitmap corresponds to one of the label values, thus a carrying body identifier with label values can be found through the bitmap index on the basis of the label values, and efficiency of carrying out data querying on the basis of the label values is improved. In addition, the bitmaps of the label values in each bitmap index partition can be determined in parallel through the preset mapping / reducing model, and efficiency of storing data is improved.

Description

technical field [0001] The present application relates to the technical field of information processing, and in particular to a data storage method, device and storage medium. Background technique [0002] Hadoop Database (HBase) has the characteristics of distributed, high reliability, high performance, and key-value (Key-Value) storage, so more and more enterprises and users use HBase to build data tables. [0003] Usually, the data table includes multiple rows of data records, and each row of data records includes the identifier of the carrier and the tag values ​​of the labels of the carrier. For example, for user A, who has two tag values ​​of gender "female" and occupation "engineer", the row corresponding to user A in the data table includes user A's identity, tag value "female" and tag value " engineer". That is, the data table records the corresponding relationship between the identifier of the carrier and the tag value it has. [0004] Based on the above-mention...
