There are so many things that need to be improved. For the StreamSets cloud user interface, there aren't enough use cases and examples for the main problems. In addition, the hybrid data sets cannot be joined in a data connector, which is a significant limitation. There aren't enough hands-on labs, and debugging is also an issue because it takes a lot of time. Logs are not that clear when you are debugging, and you can only select a single source for a pipeline. It isn't helpful when you need to apply the same logic for multiple sources. It becomes difficult because you need to create more pipelines and then add coordination between them. Initially, it's hard to find out or master the logic behind it. It can be hard if you aren't technical enough. There is scope for improvement because it's not straightforward. You need to go through the documentation and make sure that you understand every step. For me, it was a challenging model.
