[jira] [Created] (FLINK-13701) KafkaTableSourceSink doesn't support topic pattern

Shengnan YU created FLINK-13701:
-----------------------------------

             Summary: KafkaTableSourceSink doesn't support topic pattern
                 Key: FLINK-13701
                 URL: https://issues.apache.org/jira/browse/FLINK-13701
             Project: Flink
          Issue Type: Improvement
          Components: Connectors / Hadoop Compatibility
    Affects Versions: 1.8.1
            Reporter: Shengnan YU


The current  KafkaTableSourceSink can only support single topic rather than multiple or topic patterns, which is limited in many cases.

{code:java}
.connect(
  new Kafka()
    .version("0.11")   
    .topic("...")     // Here we can only set single topic
)
{code}

I lookup the source code of 1.9-release branch and there is no change. The new DDL feature is also related to the implementation of connectors. I think it is necessary to add topicPattern support.
