pyflink.datastream.connectors.kafka.KafkaSinkBuilder

class KafkaSinkBuilder

Builder to construct KafkaSink.

The following example shows the minimum setup to create a KafkaSink that writes String values to a Kafka topic.

>>> record_serializer = KafkaRecordSerializationSchema.builder() \
...     .set_topic(MY_SINK_TOPIC) \
...     .set_value_serialization_schema(SimpleStringSchema()) \
...     .build()
>>> sink = KafkaSink.builder() \
...     .set_bootstrap_servers(MY_BOOTSTRAP_SERVERS) \
...     .set_record_serializer(record_serializer) \
...     .build()

One can also configure different DeliveryGuarantee by using set_delivery_guarantee() but keep in mind when using DeliveryGuarantee.EXACTLY_ONCE, one must set the transactional id prefix set_transactional_id_prefix().

Added in version 1.16.0.
