Package org.apache.flink.formats.avro

Class AvroRowDataSerializationSchema

java.lang.Object
org.apache.flink.formats.avro.AvroRowDataSerializationSchema
All Implemented Interfaces:
Serializable, org.apache.flink.api.common.serialization.SerializationSchema<org.apache.flink.table.data.RowData>
public class AvroRowDataSerializationSchema extends Object implements org.apache.flink.api.common.serialization.SerializationSchema<org.apache.flink.table.data.RowData>
Serialization schema that serializes RowData into Avro bytes.

Serializes objects that are represented in (nested) Flink RowData. It support types that are compatible with Flink's Table & SQL API.

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