类 SchemaOperator

java.lang.Object

org.apache.flink.streaming.api.operators.AbstractStreamOperator<org.apache.flink.cdc.common.event.Event>

org.apache.flink.cdc.runtime.operators.schema.regular.SchemaOperator

所有已实现的接口:

Serializable, org.apache.flink.api.common.state.CheckpointListener, org.apache.flink.streaming.api.operators.Input<org.apache.flink.cdc.common.event.Event>, org.apache.flink.streaming.api.operators.KeyContext, org.apache.flink.streaming.api.operators.KeyContextHandler, org.apache.flink.streaming.api.operators.OneInputStreamOperator<org.apache.flink.cdc.common.event.Event,org.apache.flink.cdc.common.event.Event>, org.apache.flink.streaming.api.operators.SetupableStreamOperator<org.apache.flink.cdc.common.event.Event>, org.apache.flink.streaming.api.operators.StreamOperator<org.apache.flink.cdc.common.event.Event>, org.apache.flink.streaming.api.operators.StreamOperatorStateHandler.CheckpointedStreamOperator

@Internal
public class SchemaOperator
extends org.apache.flink.streaming.api.operators.AbstractStreamOperator<org.apache.flink.cdc.common.event.Event>
implements org.apache.flink.streaming.api.operators.OneInputStreamOperator<org.apache.flink.cdc.common.event.Event,org.apache.flink.cdc.common.event.Event>, Serializable

The operator will evolve schemas in SchemaCoordinator for incoming SchemaChangeEvents and block the stream for tables before their schema changes finish.
