Known limitations

This pre-release of the data flow capability includes several limitations and known issues that will be fixed over time.

General

The sample size for the data preview can be configured, but only up to 10000 rows.
It is not possible to fully build data flows on a tablet.
A minimum supported size for the browser window exists, but is not enforced. Reducing the window size too much will cause a poor experience with the interface.
If the source or target of a data flow refers to a space that has been renamed since the creation of the flow, it will appear valid but will fail to run. Configure your sources and targets again to fix the data flow.

Join: Supports join by field name and not by position like Qlik Talend Cloud Data Integration transformation flows.
Dates:
- The date picker in the Calculate date difference function does not display fully well.
- When formatting dates using a Date processor located after a Filter, Fork, or Unpivot processor (where the script uses a resident load statement), the function may not work.
Window: Relies on the window script function, with the same limitations.
Filter: The processors show "Undefined" as description when no field has been selected.

Collaboration from two users or more on a single data flow is limited at this time.
