org.apache.flink.formats.avro.AvroRowSerializationSchema
All Implemented Interfaces:
Serializable, org.apache.flink.api.common.serialization.SerializationSchema<org.apache.flink.types.Row>
@Internal public class AvroRowSerializationSchema extends Object implements org.apache.flink.api.common.serialization.SerializationSchema<org.apache.flink.types.Row>
Serialization schema that serializes Row into Avro bytes.

Serializes objects that are represented in (nested) Flink rows. It supports 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 AvroRowDeserializationSchema and schema converter AvroSchemaConverter.
