example 2

[0055] Among them, the definition principle of the primary key: the principle of length, generally no more than 16 bytes; the principle of uniqueness, which is used to uniquely identify a row of records; the principle of hashing, to ensure the balanced distribution of data. For example: Example 1: In the personal identity information table, if personal identity information is queried, and the ID number can uniquely represent a row of data, then the ID number can be used as the primary key. Example 2: In the personal transaction information table, date + personal ID card can be used to query the customer's transaction information on a certain day, and the method of ID number_date can be used as the primary key.

[0056] In order to meet the requirements, the defined output rules can also meet different query requirements. In one embodiment of the present application, the output rules of the above data include the structure of the output table. For example, result tables with dif...

Abstract

The invention provides a real-time computing method and a real-time computing system, the real-time computing method is executed by the real-time computing system, and the real-time computing system comprises a memory database, a real-time computing engine and a storage database. The method comprises the steps that: a memory database obtains defined structural information of a data source, processing logic of data and output rules of the data and sends the structural information, the processing logic and the output rules to a real-time calculation engine; the real-time calculation engine generates a real-time calculation task according to the structure information of the data source, the processing logic of the data and the output rule of the data, runs the real-time calculation task to obtain a calculation result, and sends the calculation result to the storage database; the storage database receives query information sent by the client and obtains a query result according to the query information and the calculation result, and the query information comprises a query request and primary key information; and the storage database sends the query result to the client. According to the method, re-programming is not needed, and real-time processing operation of data is met.

Description

technical field [0001] The present application relates to the field of data processing, in particular, to a real-time computing method and a real-time computing system. Background technique [0002] Real-time computing is aimed at massive amounts of data, and refers to a data processing framework that generates real-time uninterrupted data while meeting the application's second-level processing requirements for data. The characteristics of real-time computing are real-time data generation, real-time data transmission, real-time data calculation, and real-time display. From the perspective of the technical field, the application scenarios of real-time computing mainly include three major parts: real-time ETL and data flow, real-time data analysis, and time-driven applications. At present, representatives of the industry include Flink / Spark. [0003] Taking the current Flink real-time computing engine as an example, programming is essential, and at the same time, it is neces...
