dataset dataframe join

Hi All,

Is there any workaround/hack to join a dataset with datastream since
https://issues.apache.org/jira/browse/FLINK-2320 is still in progress.

Regards,
Vishnu

Hi Vishnu,

currently the only way to do this, is to persist the DataSet (e.g. writing
to a file) and then reading from the persisted form (e.g. file) in the open
method of a rich function in the DataStream program. That way you can keep
the data in your operator and then join with incoming stream records.

Cheers,
Till
