Abstract

The invention discloses a storage method and apparatus applied to distributed storage. The method comprises the steps of querying an original data table in distributed storage, wherein the original data table is used for storing session information of various session types; obtaining the session information corresponding to the session types; generating session character strings corresponding to the session types according to a preset storage rule, wherein the session character strings are used for recording all information in the session information; and storing the session character strings in storage fields corresponding to the session types in a session data table, wherein the session data table is used for storing all information of sessions. According to the storage method and apparatus, the technical problem of low query efficiency caused by poor table connection performance during query of the data table with many-to-many association in a column storage engine is solved.

Description

technical field [0001] The present invention relates to the field of data storage, in particular to a storage method and device applied to distributed storage. Background technique [0002] Currently, the website is usually analyzed in the form of a session. In each session, visitors can browse multiple web pages (PV), trigger multiple events (Event), and generate multiple purchase orders (Ecommerce). The above-mentioned information such as Session, PV, Event, and Economer are respectively recorded in multiple data storage tables. Each data storage table is associated through Session, where Session and other information entities are in a one-to-many relationship. [0003] When storing big data, column storage engines such as Impala are usually used. For data tables with many-to-many associations, there often exist many-to-many associations between entities. When the above-mentioned data tables with many-to-many associations are queried, the overhead of table connection s...
