The best thing about this product is that it allows you to get started quickly without any coding involved. Also, it has an easy-to-use interface for all users who are new to data analytics or machine learning applications. It also provides great documentation which helps in getting things right from day one. I have not found anything bad so far as we were able to use it at our startup. We used it while building our application called Fluidify. Since the time of its launch, there was no significant issue reported by customers regarding performance issues or downtime due to server crashes. Our main problem solved using this toolkit was handling large amounts of realtime streaming data coming from different sources like social media platforms like Facebook and Instagram etc. This helped us build dashboards for our customers faster than before.
