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

For debugging in an IDE you can execute the main method of this class using: "--defaults /path/to/sql-client-defaults.yaml --jar /path/to/target/flink-sql-client-*.jar"

Make sure that the FLINK_CONF_DIR environment variable is set.
