Perceived Cost $$$$$ [Log in to unlock pricing and user insights](/login) KL Kieran L. Small-Business (50 or fewer emp.) 2/8/2023 "Very powerful technology" 5/5 What do you like best about KX? Its speed, and the expressiveness of the language, q. The speed of development in the team is difficult to replicate in other languages. Its also a very lightweight technology that runs on standard hardware Review collected by and hosted on G2.com. What do you dislike about KX? There is a bit of an upfront cost to get the grips with the language, which can put some people off, but thankfully it's not a very large language in terms of encyclopedic learning. Review collected by and hosted on G2.com. What problems is KX solving and how is that benefiting you? We are a trading firm that uses kdb+ for our data warehousing as well as quantitative trading. We use kdb+ for data capture, storage, calculating and reacting to signals, as well as machine learning with python plugins. I suspect our team is smaller in size than comparable teams, in large part due to the productivity gains to be had with kdb+ Review collected by and hosted on G2.com.

Director - Quant Development Financial Services Enterprise (\> 1000 emp.) 8/1/2023 "A beautiful and powerful query language and database for structured data" 5/5 What do you like best about KX?

KDB core is extremely capable of capturing and processing large volumes of timeseries data. Even after 20 years, it still produces moments of "wow, that was fast". The documentation has improved dramatically, barrier to entry reduced and the community of developers/number of partners has grown as a result. With the appropriate skills and experience, the q language and KDB are hard to beat for elegant and efficient timeseries analysis. Review collected by and hosted on G2.com. What do you dislike about KX? The open frameworks and ancillary services solve a lot of the common problems and improved APIs increase access to the underlying data, but the core product is still quite raw and protection from bad user queries is still limited. Review collected by and hosted on G2.com. What problems is KX solving and how is that benefiting you? Capture and analysis of timeseries data to support and optimise systematic trading systems.

After working in the industry for 4 years it has been great learning about the core technology of KDB+, and also seeing the updates and improvements that are still being published. Review collected by and hosted on G2.com. What do you dislike about KX? There can be a higher barrier for entry as it does take some time to learn about the technology, but it has done a great job integrating with other services. Review collected by and hosted on G2.com. What problems is KX solving and how is that benefiting you? The ability to integrate everything from loading to visualizing the data for the client using KX products is essential for my day-to-day work. Using kdb+ to store data and Kx Dashboard for visualization, and also helping client potentially migrate to newer KX services. Review collected by and hosted on G2.com.

Its performance is second-to-none when it comes to process large time-series based tables. Review collected by and hosted on G2.com. What do you dislike about KX? To best architect a solution, one will have to program in Q, which can be challenging to some people. Review collected by and hosted on G2.com.

KDB is an exceptional database. The built-in programming language, q, is exceptionally powerful and versatile. It allows us to build very flexible apis, stream low latency trading stats, administer our database, monitor trade performance and adds business value in many many other ways. Review collected by and hosted on G2.com. What do you dislike about KX? There are very few downsides apart from the perceived learning curve to pick up the lanague, which I think is overstated. There are a few potential improvements around multithreadding, which could be a big help, but I've been told they're coming in v4.1 which will be very useful!
