Trial Software
A trial version of kdb+ is freely available for non-commercial use, and is ideal for learning
the q programming language.
Evaluations
Kx offers free on-site evaluations for prospects that we qualify as having application requirements that suit kdb+. Experienced consultants run these on your data, your hardware and your queries.
We do not provide generic benchmarks, because these typically do not reflect real-world use. Instead, we advise running a realistic evaluation on your own data and queries. At the same time, you can see how easy it is to customize kdb+ for your requirements.
For requirements and testing that could not be accomplished in a typical 2-3 week free evaluation, extended proof-of-concept trials are offered for a fee by our Consulting Partners.
