----------------------------------
hi ,[~till.rohrmann],In order to ensure the compatibility of subsequent code. i
think should change
FlinkKafkaConsumerBase ,such as add one class KafkaTopicAndPartition and one
interface KafkaDescriptor ,KafkaTopicAndPartition and KafkaTopicsDescriptor
implements KafkaDescriptor,FlinkKafkaConsumerBase's
topicsDescriptor change to KafkaDescriptor,then FlinkKafkaConsumerBase add one
Constructor，this constructor modify
this.kafkaDescriptor = new
KafkaTopicsAndPartitionDescriptor(topicAndPartitions, topicAndPartitionPattern);
may be have better ways ,welcome the discussion
> FlinkKafkaConsumer should support assgin partition

> i find flink 1.7 also has universal Kafka connector ,if the kakfa-connector
> support assgin partition ,the the kakfa-connector should prefect. such as a
> kafka topci has 3 partition, i only use 1 partition,but i should read all
> partition then filter.this method Not only waste resources but also
> relatively low efficiency.so i suggest FlinkKafkaConsumer should support
> assgin partition
