org.apache.flink.streaming.connectors.kafka.table

类 UpsertKafkaDynamicTableFactory.DecodingFormatWrapper

java.lang.Object

org.apache.flink.streaming.connectors.kafka.table.UpsertKafkaDynamicTableFactory.DecodingFormatWrapper

所有已实现的接口:

org.apache.flink.table.connector.format.DecodingFormat<org.apache.flink.api.common.serialization.DeserializationSchema<org.apache.flink.table.data.RowData>>, org.apache.flink.table.connector.format.Format

封闭类:

UpsertKafkaDynamicTableFactory

protected static class UpsertKafkaDynamicTableFactory.DecodingFormatWrapper
extends Object
implements org.apache.flink.table.connector.format.DecodingFormat<org.apache.flink.api.common.serialization.DeserializationSchema<org.apache.flink.table.data.RowData>>

It is used to wrap the decoding format and expose the desired changelog mode. It's only works for insert-only format.
