It is easy to use, it has great support for many languages including Python (which I am using). The GUI could be more intuitive but this isn't really an issue since most of my work flows are done through scripts anyways so its not that important in general - just pick something you're comfortable with! Great tool if your looking into streaming data from multiple sources or other tools like Kafka etc., which can sometimes get messy when dealing directly w/streaming systems such as Kinesis DataStreams vs Sql Server Streaming Services via SSIS packages.
