I was looking for a functional programming solution that would allow us to perform calculations in real-time with high performance. After doing some research, I found knoldus. Their solution allowed me to write functions in Scala, a functional language, that performed calculations in real-time and gave me the flexibility to deploy the function across multiple nodes. It has allowed my team to accomplish a lot more in less time. I have worked with other vendors before who tried to sell us a functional solution but it did not meet our requirements. They were too rigid and required that we learn their API. When I came across knoldus, they were willing to adapt to our business needs and understand what we needed. I could easily move from development to production without worrying about compatibility. Their documentation is excellent and their engineers helped us when we had problems. They went above and beyond the call of duty.
