类 TableBufferReducedStatementExecutor

java.lang.Object

org.apache.flink.connector.jdbc.internal.executor.TableBufferReducedStatementExecutor

所有已实现的接口:

JdbcBatchStatementExecutor<org.apache.flink.table.data.RowData>

public final class TableBufferReducedStatementExecutor
extends Object
implements JdbcBatchStatementExecutor<org.apache.flink.table.data.RowData>

Currently, this statement executor is only used for table/sql to buffer insert/update/delete events, and reduce them in buffer before submit to external database.
