类 AvroRowDeserializationSchema

java.lang.Object

org.apache.flink.api.common.serialization.AbstractDeserializationSchema<org.apache.flink.types.Row>

org.apache.flink.formats.avro.AvroRowDeserializationSchema

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 class AvroRowDeserializationSchema
extends org.apache.flink.api.common.serialization.AbstractDeserializationSchema<org.apache.flink.types.Row>

Deserialization schema from Avro bytes to Row.

Deserializes the byte[] messages into (nested) Flink rows. It converts Avro types into types that are compatible with Flink's Table & SQL API.

Projects with Avro records containing logical date/time types need to add a JodaTime dependency.

Note: Changes in this class need to be kept in sync with the corresponding runtime class AvroRowSerializationSchema and schema converter AvroSchemaConverter.

AvroRowDeserializationSchema

public AvroRowDeserializationSchema(Class<? extends org.apache.avro.specific.SpecificRecord> recordClazz)

已过时。

Creates a Avro deserialization schema for the given specific record class. Having the concrete Avro record class might improve performance.

参数:

recordClazz - Avro record class used to deserialize Avro's record to Flink's row

AvroRowDeserializationSchema

public AvroRowDeserializationSchema(String avroSchemaString)

已过时。

Creates a Avro deserialization schema for the given Avro schema string.

参数:

avroSchemaString - Avro schema string to deserialize Avro's record to Flink's row
