------------------------------------
Summary: Support consuming multiple topics for KafkaTableSource
Key: FLINK-18714
URL: https://issues.apache.org/jira/browse/FLINK-18714
Project: Flink
Issue Type: Improvement
Components: Table SQL / Planner
Affects Versions: 1.11.0
Reporter: hailong wang
Fix For: 1.12.0
SQL one kafka table only supports one topic by `{{'topic' = 'topic1'}}` or
`{{'connector.topic' = 'topic1'}}`.
We can support consuming multiple topics in one kafka table.
My idea is that We can concatenate multi topic with comma just like,
`{{'topic' = 'topic1,topic2,topic3'}}`
