类 ChangelogCsvDeserializer

java.lang.Object

org.apache.flink.table.examples.java.connectors.ChangelogCsvDeserializer

所有已实现的接口:

Serializable, org.apache.flink.api.common.serialization.DeserializationSchema<org.apache.flink.table.data.RowData>, org.apache.flink.api.java.typeutils.ResultTypeQueryable<org.apache.flink.table.data.RowData>

public final class ChangelogCsvDeserializer
extends Object
implements org.apache.flink.api.common.serialization.DeserializationSchema<org.apache.flink.table.data.RowData>

The ChangelogCsvDeserializer contains a simple parsing logic for converting bytes into Row of Integer and String with a RowKind.

The final conversion step converts those into internal data structures.
