----------------------------------
In FlinkKafkaConsumer, the constructor method as the follow:
{code:java}
//single
public FlinkKafkaConsumer(String topic, KafkaDeserializationSchema<T>
deserializer, Properties props) {
this(Collections.singletonList(topic), deserializer, props);
}
//list
public FlinkKafkaConsumer(List<String> topics, DeserializationSchema<T>
deserializer, Properties props) {
this(topics, new KafkaDeserializationSchemaWrapper<>(deserializer), props);
}
//pattern
public FlinkKafkaConsumer(Pattern subscriptionPattern, DeserializationSchema<T>
valueDeserializer, Properties props) {
this(null, subscriptionPattern, new
KafkaDeserializationSchemaWrapper<>(valueDeserializer), props);
}{code}
There are already three types.

> In streaming api, we can use regex to find topic and enable partiton
> discovery by setting non-negative value for
> `{{flink.partition-discovery.interval-millis}}`. However, it's not work in
> table api. I think we can add options such as 'topic-regex' and
> '{{partition-discovery.interval-millis}}' in WITH block for users.
