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
