Thanks, Gordan!  Will keep an eye on that!

Hi Connie,

We do have a pull request for the feature, that should almost be ready after rebasing: https://github.com/apache/flink/pull/3915, JIRA: https://issues.apache.org/jira/browse/FLINK-6352.
This means, of course, that the feature isn't part of any release yet. We can try to make sure this happens for Flink 1.5, for which the proposed release date is around February 2018.

Cheers,
Gordon

Hi,

 

Does Flink-Kafka connector allow job graph to consume topoics/partitions from a specific timestamp?

 

https://github.com/apache/flink/blob/master/flink-connectors/flink-connector-kafka-base/src/main/java/org/apache/flink/streaming/connectors/kafka/FlinkKafkaConsumerBase.java#L469 seems to suggest that a job graph can only start from an earliest, latest or a set of offsets.

 

KafkaConsumer API, https://github.com/apache/kafka/blob/trunk/clients/src/main/java/org/apache/kafka/clients/consumer/KafkaConsumer.java#L1598, gives us a way to find partition offsets based on a timestamp.

 

Thanks

Connie
