Jiangjie Qin commented on FLINK-18780:
--------------------------------------
It is a little unfortunate that `FlinkKafkaProducer` has 11 public constructors
among which 5 are deprecated and 6 are still maintained. To be honest I'd
prefer a builder pattern to adding more constructors to it. For existing users,
one may just call:
FlinkKafkaProducer(String, SerializationSchema<IN>, Properties, null, Semantic,
DEFAULT_KAFKA_PRODUCERS_POOL_SIZE).
> FlinkKafkaProducer should add another constructor accepting
> SerializationSchema

> Reporter: Qingsheng Ren
