KafkaSerializationSchema (Flink : Connectors : Kafka 3.3.0-1.19 API)

Type Parameters:

T - the type of values being serialized

All Superinterfaces:

Serializable

All Known Implementing Classes:

KafkaSerializationSchemaWrapper
```
@PublicEvolving
@Deprecated
public interface KafkaSerializationSchema<T>
extends Serializable
```
Deprecated.
Will be turned into internal API when FlinkKafkaProducer is removed.

A KafkaSerializationSchema defines how to serialize values of type T into ProducerRecords.
Please also implement KafkaContextAware if your serialization schema needs information about the available partitions and the number of parallel subtasks along with the subtask ID on which the Kafka Producer is running.

```
default void open(org.apache.flink.api.common.serialization.SerializationSchema.InitializationContext context)
           throws Exception
```
    Deprecated.
    
    Initialization method for the schema. It is called before the actual working methods serialize(Object, Long) and thus suitable for one time setup work.
    The provided SerializationSchema.InitializationContext can be used to access additional features such as e.g. registering user metrics.
    
    Parameters:
    
    context - Contextual information that can be used during initialization.
    
    Throws:
    
    Exception
