类 CsvRowDeserializationSchema

java.lang.Object

org.apache.flink.formats.csv.CsvRowDeserializationSchema

所有已实现的接口:

Serializable, org.apache.flink.api.common.serialization.DeserializationSchema<org.apache.flink.types.Row>, org.apache.flink.api.java.typeutils.ResultTypeQueryable<org.apache.flink.types.Row>

已过时。

The format was developed for the Table API users and will not be maintained for DataStream API users anymore. Either use Table API or switch to Data Stream, defining your own DeserializationSchema.

@PublicEvolving
 @Deprecated
public final class CsvRowDeserializationSchema
extends Object
implements org.apache.flink.api.common.serialization.DeserializationSchema<org.apache.flink.types.Row>

Deserialization schema from CSV to Flink types.

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

Failure during deserialization are forwarded as wrapped IOExceptions.
