Abstract

The invention belongs to the field of data processing, and discloses an SQL data real-time processing method and device based on Flink, computer equipment and a readable storage medium. The method comprises the steps of storing data input by a user in tidb through a client, then classifying SQL statements in an sql data table in an flink cluster to obtain classified SQL statements, and correspondingly packaging the classified SQL statements to generate a job operator; and the job operators are connected in series according to the logic of the SQL statement to generate an operator flow, and theoperator flow is submitted to a taskmanger for execution, so that real-time processing of SQL data is realized. By adopting the method to encapsulate the SQL statement, a user can replace writing ofa large number of Java codes with a small number of SQL codes, and the technical problem that in the prior art, implementation of SQL data processing through flink is complex is solved. The inventionfurther relates to a blockchain technology, and the data input by the user can be stored in the blockchain node.

Description

technical field [0001] The present application relates to the field of data processing, in particular to a method, device, computer equipment and storage medium for real-time processing of SQL data based on Flink. Background technique [0002] Flink SQL is a development language that conforms to standard SQL semantics and is designed for Flink real-time computing to simplify the computing model and lower the threshold for users to use real-time computing. The cost of open source Flink programming development is high, the learning cost is high, the debugging is complicated, and the online cycle is long. Different development methods are used for each data source connection, which consumes a lot of learning costs and development time. When Flink is applied to the real-time processing of SQL data, in order to realize functions such as source, sink, and dimension tables, users need to inherit various functions (functions) of Flink for development, and dimension tables also need...
