RocketMQSink(KeyValueSerializationSchema<IN> schema, TopicSelector<IN> topicSelector, Properties props) missing in master branch

hello, guys
At master branch, I donot see class
RocketMQSink(KeyValueSerializationSchema schema, TopicSelector topicSelector, Properties props), but RocketMQSink(Properties props). Do I checkout wrong branch?

Start by checking the RocketMQSink class on the master branch and compare its available constructors with the signature shown in the issue. Verify whether the report is caused by the wrong branch or a missing API; done means establishing the expected constructor state and documenting or correcting the discrepancy.
