The q language allows for incredible amounts of work to be done with comperatively little. People who demonstrate great skill are capable of incredibly quick prototyping and exploration of both data and ideas. The ecosystem with Q-Studio and the ease of use for initial data exploration is incredible and I find it much quicker than spinning up the proper python script or sql query to accomplish the same thing. The underlying database has very strong performance on tick based market data. Review collected by and hosted on G2.com. What do you dislike about KX? The Q language has some of the worst error messaging I have ever experienced. The learning curve ends up being extremely taxing since solving problems can take far longer than it would take in a comperable product. The free book does a great deal of work to alleviate this but I think the effort to increase clarity of error messaging would be worth the costs. Review collected by and hosted on G2.com. What problems is KX solving and how is that benefiting you? KX is solving the problem of storing all market data used by the firm and offering quants and analysts insight into different aspects. Compared to OneTick, the previous solution, KX offers a much improved overall experience. Review collected by and hosted on G2.com.

Mid-Market (51-1000 emp.) 5/24/2023 "Excellent performance and productivity" 5/5 What do you like best about KX? It's a very powerful, flexible and high performance system. It's really a programming language which also has a database, which brings a great deal of flexibility. The language, q, provides very succinct ways of expressing relatively complex operations. There aren't many systems that provide capabilties to operate on all of streaming, in-memory and storage backed data. The community of developers is small, but accessible and helpful. Review collected by and hosted on G2.com. What do you dislike about KX? The programming language, q, can be a double edged sword- there is a (sometimes overstated) learning curve. The learning curve is related to both the syntax and the mindshift change required when coming to a vector language from a more traditional programming background. The upside though is the expressiveness and productivity achieved when the curve is overcome. The standard tooling is limited- you end up building a lot which you don't have to with other systems, but then because people like the language and system they sometimes end up buliding too much which would be better done in other ways. Review collected by and hosted on G2.com. What problems is KX solving and how is that benefiting you? All the problems associated with time series data storage, management and analysis.

Willingness to partner with users and customers Good support across multiple channels (email, forums, listbox) Timely release of features to address emerging developments (eg., vector db) Review collected by and hosted on G2.com. What do you dislike about KX? Tutorials require understanding of KDB+ to resolve issues. A better managed learning management system will greatly help in adoption. Needs to foster a more collaborative approach - eg., open sourcing pyKx was a great step. Other features such as REST API should be ideally released to the public so that access to basic functionalities are made more widely accessible Review collected by and hosted on G2.com. What problems is KX solving and how is that benefiting you? Kx supports all major enterprise needs for high-performance computing especially with large TB-PB scale databases that would otherwise take 10x the number of resources and 10x the cost.

CM Chris M. Founder Small-Business (50 or fewer emp.) 9/18/2023 "KDB is second-to-none for wrangling time series data" 5/5 What do you like best about KX? Fast, efficient, highly expressive terse syntax that is beautifully designed and well considered. The ability to mix programming and database primitives together can lead to some very elegant solutions. KDB Developer is a nice addition for EDA/charting. Performance is as fast as the metal allows, and use of multicore is transparent and easy. Review collected by and hosted on G2.com. What do you dislike about KX?

AF Andrew F. Head of Trading Analytics Enterprise (\> 1000 emp.) 5/30/2023 "Have been a business sponsor of KX for over 20 years using to support many businesses" 5/5 What do you like best about KX? Fundamentally KX core value was always about speed and efficiency. In the early days they didnt have many user tooling so you needed to find experts that were few and far between but at the end of the day the performance was differentiating and still is. Their focus on speed and minimising space for data is still their edge. They have evolved their tooling to make adoption easier but their underlying power is still their strength. Review collected by and hosted on G2.com. What do you dislike about KX? It really depends on your perspective. It takes more effort than simpler languages to get things up and running. but if your target is scalable and you want a strong foundation like anything you have to put the effort in. From my perspective there are no dislikes other than the community is still perhaps too small Review collected by and hosted on G2.com.

Enterprise Service Manager Mid-Market (51-1000 emp.) 6/6/2023 "User, partner and enthusiast" 5/5 What do you like best about KX? Completeness of the solution. Streaming analytics, data and analytics in memory and analysis of historical data on disk in a single solution is unique. KX can do everything another time series database can do but faster and more efficienctly - it also has unique temporal analytics capabilities others have never been able to replicate. Review collected by and hosted on G2.com. What do you dislike about KX? The amount of times the user community has solved the same problems in marginally different ways. A managed cloud service on aws, open sourcing pykx and standardising kdb architect through kdb Insights are great steps forward to address this and allow builders to focus on outcomes rather than plumbing.

KX is a beautiful solution for running analytics on large data sets, particularly when time series is involved. Its structure leads to elegant code and small systems that are easy to maintain and cheap to run while delivering performance orders of magnitude better than the competition. After 20+ years of dominating electronic trading analytics on Wall Street, its latest version with Python integration and cloud interoperability leaves it ideally placed to capitalise on growing data analytics needs in other areas, notably Artificial Intelligence. Review collected by and hosted on G2.com. What do you dislike about KX? People often say it's difficult to learn, but the reality is that the analytics it supports would be far more difficult to achieve using other "easy" languages and data stores.

Kx has an extremely minimal language, and though it looks foreign at first it is actually quite simple and barebones. This simplicity allows you to work on the essential complexity of your problem instead of the incidental complexity added by the tools. Having used many of the popular alternatives, databricks/clickhouse/hadoop/pandas/polars none achieve the simplicity and elegance provided by this platform. Review collected by and hosted on G2.com. What do you dislike about KX? Kx is a proprietary product this prevents mass adoption. This makes integrating with other tools harder. Recent releases of pykx and pgwire have made massive strides towards integrating with the larger ecosystem. Review collected by and hosted on G2.com. What problems is KX solving and how is that benefiting you? Kx allows us to see real-time trends in a client-facing business. Also, when debugging large datasets, nothing beats q for slicing and dicing the data. Review collected by and hosted on G2.com.

KX makes light work of intricate time series transformations on vast amounts of data. Review collected by and hosted on G2.com. What do you dislike about KX? This is an area currently at the forefront of focus for KX, with the recent release of PyKx. But making an easy interface to the rich ocean of data vizualization / ML libraries etc in Python is something I've been excited about for a while. Review collected by and hosted on G2.com.
