Package org.apache.flink.table.client

Class SqlClient

java.lang.Object

org.apache.flink.table.client.SqlClient

public class SqlClient
extends Object

SQL Client for submitting SQL statements. The client can be executed in two modes: a gateway and embedded mode.

- In embedded mode, the SQL CLI is tightly coupled with the executor in a common process. This allows for submitting jobs without having to start an additional component.

- In gateway mode, the SQL CLI client connects to the REST API of the gateway and allows for managing queries via console.
