It's easy to learn if you know SQL and Python. There are many tutorials for beginners. The support team is very good and helpful. We like that we can integrate with other tools such as Apache Oltu or Tableau. In some cases it's not working properly (we need to correct it ourselves). Also, sometimes the code does not work in all versions of Python (we need to update the code several times until the problem disappears), but this is a small detail. I love Astronomer because it allows us to analyze our data without having to invest time programming and creating reports. We have been able to do everything using Astronomer and we have saved a lot of time.
