What's New in RapidMiner Server 9.0.3?

Due to a change in the metadata generation logic, customers that already have migrated to version 9.x might encounter missing metadata for some data sets. The missing metadata can be generated with either RapidMiner Studio or a Job Agent with version 9.0.3 or above. To generate the missing metadata, use the Retrieve operator to load the data set and store it to the same location with the Store operator again.

Released: October 4th, 2018
