> Allow usage of custom implementation of Kafka Producer and Consumer in source
> and sink
> --------------------------------------------------------------------------------------

> Key: FLINK-11319
> URL: https://issues.apache.org/jira/browse/FLINK-11319
> Project: Flink
> Issue Type: Improvement
> Components: Connectors / Kafka
> Reporter: Allen Wang
> Priority: Major
> Labels: stale-major
>
> We use our own implementation of Kafka producer and consumer in our cloud
> environment for better integration with our infrastructure. The {{Consumer}}
> and {{Producer}} interfaces are properly implemented, but the implementation
> does not extend {{KafkaConsumer}} or {{KafkaProducer}}. Instead, it wraps and
> decorates the instance of the default Kafka implementation.
> I propose the following changes to make it easy to hook up our own
> implementation with Flink.
> * Refer to {{Consumer}} and {{Producer}} interface, not {{KafkaConsumer}} or
> {{KafkaProducer}} in {{FlinkKafkaInternalProducer}} and
> {{KafkaConsumerThread}}
> * Add {{ConsumerBuilder}} and {{ProducerBuilder}} interface with the
> following definition
> {code:java}
> // ProducerBuilder
> Producer<K, V> build(Properties properties)
> // ConsumerBuilder
> Consumer<byte[], byte[]> build(Properties properties){code}
> * Add new constructors in {{FlinkKafkaProducer}} and {{FlinkKafkaConsumer}}
> to pass in the {{ProducerBuilder}} and {{ConsumerBuilder}}.
