sink

public static <T> org.apache.flink.streaming.api.functions.sink.SinkFunction<T> sink(String sql,
                                                                                     JdbcStatementBuilder<T> statementBuilder,
                                                                                     JdbcExecutionOptions executionOptions,
                                                                                     JdbcConnectionOptions connectionOptions)

Create a JDBC sink.

Note: the objects passed to the return sink can be processed in batch and retried. Therefore, objects can not be reused.

类型参数:

T - type of data in StreamRecord.

参数:

sql - arbitrary DML query (e.g. insert, update, upsert)

statementBuilder - sets parameters on PreparedStatement according to the query

executionOptions - parameters of execution, such as batch size and maximum retries

connectionOptions - parameters of connection, such as JDBC URL

exactlyOnceSink

public static <T> org.apache.flink.streaming.api.functions.sink.SinkFunction<T> exactlyOnceSink(String sql,
                                                                                                JdbcStatementBuilder<T> statementBuilder,
                                                                                                JdbcExecutionOptions executionOptions,
                                                                                                JdbcExactlyOnceOptions exactlyOnceOptions,
                                                                                                org.apache.flink.util.function.SerializableSupplier<XADataSource> dataSourceSupplier)

Create JDBC sink which provides exactly-once guarantee.

Note: the objects passed to the return sink can be processed in batch and retried. Therefore, objects can not be reused.

类型参数:

T - type of data in StreamRecord.

参数:

sql - arbitrary DML query (e.g. insert, update, upsert)

statementBuilder - sets parameters on PreparedStatement according to the query

executionOptions - parameters of execution, such as batch size and maximum retries

exactlyOnceOptions - exactly-once options. Note: maxRetries setting must be strictly set to 0 for the created sink to work properly and not to produce duplicates. See issue FLINK-22311 for details.

dataSourceSupplier - supplies the XADataSource
