Data Refinery and Profiling Changes in Watson Studio and Watson Knowledge Catalog
By: Snehal Gawas
Two changes related to Watson Studio and Watson Knowledge Catalog
Shaping data and running data refinery flows will use enhanced spark environments that add flexibility and change the capacity unit hours needed.
Data profiling and classification will be available from Watson Knowledge Catalog only.
Enhanced spark environments to shape data and run data refinery flows
Data refinery provides data preparation and visualization capabilities in both Watson Studio and Watson Knowledge Catalog. You use data refinery to shape your data and run data flows to create new datasets for your analytical projects. We use Capacity Unit-Hours as the unit of measure for the amount of processing consumed to run data refinery flows. Each Watson Studio or Watson Knowledge Catalog plan includes a set amount of Capacity Unit-Hours (CUH). Overage is charged as per-plan when the account has used up the included amount of CUHs.
Currently, data refinery flows use a dedicated Spark cluster that requires 6 Capacity Units per hour. In addition, there is a minimum charge of 0.96 Capacity Unit-Hours each time you initiate a data flow job.
Effective May 17, 2019, data refinery flows will run using the default Spark environment and require only 1.5 Capacity Units per hour, which is lower than the current rate and provides greater value. We are also removing the minimum charge related to running data flows.
However, effective July 12, 2019, shaping data in the interactive UI will start consuming Capacity Units per hour. Note that this is a new charge. Here are some data refinery usage examples and their associated CUH consumption:
If you need additional processing capacity for big data flows, you can select another custom Spark environment. The associated capacity unit hours can vary based on the performance specified. Learn more about custom Spark environments here. Effective July 12, 2019, a user will also get an option to select a non-distributed R runtime for data flow runs.
These changes provide three key benefits:
Reduced rates when running data refinery flows using the default Spark environment
Greater flexibility in selecting the appropriate Spark environment for the job
A pricing model that reflects the actual usage of data refinery services
Data profiling and classification available only with Watson Knowledge Catalog
Data profiling and classification processes samples of data assets to extract statistics and insights on their content. It includes whether the data contain personal or sensitive information, such as names, emails, national identifications, and credit card numbers. You can access the data profile from the Profile tab when viewing the data asset in a project or catalog.
Currently, you can run profiling and classification if you have either Watson Studio or the Watson Knowledge Catalog. Effective July 12, 2019, you must have Watson Knowledge Catalog in order to run profiling or access the profile of a data asset from a project or a catalog.
Please note that the profile and classification feature (available on the preview of data in the project or catalog) is different than the profile tab in the Data Refinery tool. There are no changes in the profile tab of the Data Refinery tool.
There is no change to the current number of capacity units needed to run profiling jobs at 6 Capacity Units per hour. A minimum charge of 0.96 Capacity Unit-Hours applies each time you run a profiling job. The consumed capacity units will be deducted from the set amount included with the provisioned Watson Knowledge Catalog plan.
How to access profiling and classification
Note that the sign-up process for Watson Studio includes the no-cost Lite plan of Watson Knowledge Catalog by default. Therefore, unless you have explicitly removed the Watson Knowledge Catalog app from the account or during the sign-up process, you can continue to access profiling services from the included Watson Knowledge Catalog Lite plan.
If you only have Watson Studio and want continued access to data profiling, you can add Watson Knowledge Catalog to your account at any time.
For both of these updates, there are no changes in price metrics for CUH (0.50 USD/Capacity Unit-Hour). For the most up-to-date pricing and plans, please refer to the catalog pages for Watson Studio and Watson Knowledge Catalog.
