The most valuable features assist with understanding data formats and transforming data.
What needs improvement?
The tool requires you to write a lot of code in Java and XSLT, which makes development tough. There are other tools such as Dell Boomi that do not need as much coding. The initial setup can be made a little easier. Support for microservices is somewhat lacking.
Which solution did I use previously and why did I switch?
I have experience with a few similar solutions from different vendors. One of them is MuleSoft, which is leading in the support for microservices but are concentrating on API-related tasks.
What other advice do I have?
In summary, this is a good product but I would prefer one that requires less code. I would rate this solution a seven out of ten.
