java.lang.Object

org.apache.flink.formats.json.JsonRowDataSerializationSchema

All Implemented Interfaces:

Serializable, org.apache.flink.api.common.serialization.SerializationSchema<org.apache.flink.table.data.RowData>

@Internal
public class JsonRowDataSerializationSchema
extends Object
implements org.apache.flink.api.common.serialization.SerializationSchema<org.apache.flink.table.data.RowData>

Serialization schema that serializes an object of Flink internal data structure into a JSON bytes.

Serializes the input Flink object into a JSON string and converts it into byte[].

Result byte[] messages can be deserialized using JsonRowDataDeserializationSchema.
