> Key: FLINK-22748
> URL: https://issues.apache.org/jira/browse/FLINK-22748
> Project: Flink
> Issue Type: Improvement
> Components: Connectors / Kafka, Table SQL / Ecosystem
> Reporter: Timo Walther
> Assignee: Nicholas Jiang
> Priority: Major
> Labels: pull-request-available, starter

> We should allow to write to different Kafka topics based on some column value in SQL.
> The existing implementation can be easily adapted for that. The "target topic" would be an additional persisted metadata column in SQL terms. All one need to do is to adapt
> DynamicKafkaSerializationSchema
> KafkaDynamicSink
> We should guard this dynamic behavior via a config option and make the topic option optional in this case.
