Class CsvRowDataDeserializationSchema

java.lang.Object

org.apache.flink.formats.csv.CsvRowDataDeserializationSchema

All Implemented Interfaces:

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>

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

Deserialization schema from CSV to Flink Table & SQL internal data structures.

Deserializes a byte[] message as a JsonNode and converts it to RowData.

Failure during deserialization are forwarded as wrapped IOExceptions.
