Abstract

The invention provides a data query method and device. The method comprises the steps of receiving a query language input by a terminal, wherein the query language carries query parameters; according to the query parameter and a query statement template corresponding to the query language, obtaining a query statement, the query statement template being pre-stored in a template library; and obtaining target data corresponding to the query language based on the query statement and feeding back to the terminal.

Description

technical field [0001] This application relates to the field of data query, and the following description relates to a data query method and device. Background technique [0002] Strategic systems (such as recommendation systems, search systems, etc.) are usually divided into two parts: offline and online, all of which require batch, streaming, or online real-time query operations on data. The data source of the queried data is usually structured It is personalized and diverse, such as from mysql, hdfs, hive, and also from kafka, elasticsearch, etc. And each data source corresponds to a query syntax. Developers need to manage various data service clients and translate them into different query languages ​​in combination with business logic for query. The biggest problem brought about by this is the problem of data management and query. The complexity becomes high and the development efficiency is low. Based on the above problems, in order to reduce the difference in the st...
