Upsolver Review
Pros
Can handle very large amounts of data (10's of terabytes) reliably with ease and is overall a very powerful product to use. Also has fantastic customer service.
Cons
Although the customer service is great, it may be necessary to consult them multiple times while trying to figure out some of the more powerful features of Upsolver.
Geat experience, save me a lot of time and money for DevOps and BigData Analytics
The system shortened development times, saved manpower and infrastructure
Pros
Saves great development time
Does not require a large team for development and maintenance
Amazing customer service!
Cons
A relatively long study time,
The system is still in development so with time there are more options so you need some patience, but you can say that every problem I had was resolved quickly

Upsolver's service solved me a big problem in no time
Pros
Handles 10s of TBs easily. The data is aggregated very reliably. The stream is updated on a near real time basis. Great customer service.
Cons
Some features require a 1:1 explanation session, cause they're not easy to understand. The team is really responsive though, so it's not a big problem.
