Embodiment 1

[0024] According to an embodiment of the present invention, an embodiment of a session screening method is provided. It should be noted that the steps shown in the flowcharts of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and, although A logical order is shown in the flowcharts, but in some cases the steps shown or described may be performed in an order different from that shown or described herein.

[0025] figure 1 is a flow chart of a session screening method according to an embodiment of the present invention, such as figure 1 As shown, the method includes the following steps:

[0026] Step S102, acquiring a custom index for filtering sessions, wherein the custom index includes an index element and at least one dimension element.

[0027] In an optional solution, the above-mentioned custom index may be a tuple index, and it may be determined that the tuple index includes an index element and at least o...

Embodiment 2

[0074] According to an embodiment of the present invention, an embodiment of a session screening device is provided, such as figure 2 As shown, the device includes: a first acquisition unit 21 , an extraction unit 23 and a first processing unit 25 .

[0075] Wherein, the first acquiring unit 21 is configured to acquire a custom index used for screening sessions, wherein the custom index includes an index element and at least one dimension element.

[0076] In an optional solution, the above-mentioned custom index may be a tuple index, and it may be determined that the tuple index includes an index element and at least one dimension element according to the user's filtering requirements.

[0077] For example, the above embodiments of the present invention will be described by taking the user's need to filter the number of high-quality sessions as an example. Custom indicators can be defined according to user needs. The custom indicators can include an indicator element and tw...

Abstract

The invention discloses a session screening method and apparatus. The method comprises the steps of obtaining a self-defined index used for screening sessions, wherein the self-defined index contains an index element and at least one dimension element; according to the self-defined index, extracting a data table set from multiple data tables, wherein each data table in the data table set at least contains any one of the following elements: the index element and the at least one dimension element; and extracting the session with the self-defined index meeting a preset condition from the data table set, and obtaining the screened session. According to the method and the apparatus, the technical problem of resource waste caused by a complex session screening process due to poor correlation of the data tables in a distributed database in the prior art is solved.

Description

technical field [0001] The invention relates to the field of distributed databases, in particular to a session screening method and device. Background technique [0002] In a distributed environment, currently commonly used query engines include structured databases with metadata such as Hive and Impala. In these structured databases with metadata, generally, the data of various events are recorded in various fact data tables. In the process of users accessing the Internet, there are generally various fact data tables representing user access behaviors such as session table (Session), page view table (PageView) and order table (Order), and these data tables can be identified by the user's session ID ( SessionID) to form all entities of the entire session. However, due to the poor correlation between data tables, when users need to obtain indicator data and dimension data in multiple fact data tables from multiple dimensions, multiple screenings are required, and the screen...
