- fidotron 1y ago> A quick look at the product licensing page reveals that KDB-X gives you up to 16GB of RAM, 4 secondary threads per process, and 8 IPC connections.
- willvarfar 1y agoIt also says it is not for production use.
- latenightcoding 1y agoWith the rise of LLM-coding do these specialized/niche languages lose their edge? (i.e: prototyping speed, job security, etc)
- therein 1y agoIn this case it is a little beyond specialized and niche. It is right to left too. https://news.ycombinator.com/item?id=44498766 https://news.ycombinator.com/item?id=44498766
- AUnterrainer 1y agoNo LLM can write KDB yet
- pinewurst 1y agoAs most KDB code is proprietary, one wonders if there's even enough available code to train/steal from.
- AUnterrainer 1y agoKDB code is as proprietary as java, python, C++ code found at other financial institutions. What's proprietary is the Q language. not the code you write with it
- resoluteteeth 1y agoI think what they mean is that there is less publicly available kdb code for llms to be trained on
- coredog64 1y agoNo "public" LLM can write KDB yet.
- starkparker 1y agoContext for people lacking it: - Blog announcement: https://kx.com/blog/introducing-kdb-x-public-preview/ https://kx.com/blog/introducing-kdb-x-public-preview/ - Product landing page: https://kx.com/products/introducing-kdb-x-public-preview/ https://kx.com/products/introducing-kdb-x-public-preview/
- kristjansson 1y agoLink should be changed to this from the current blogslop
- KerrAvon 1y agofor anyone else looking for tl;dr on WTF KDB actually is, it's buried in the AI slop marketing text in the blog announcement: "KDB-X is […] both a programming language and a database."
- leprechaun1066 1y agoThe overview here is better than the marketing: https://code.kx.com/q4m3/0_Overview/ https://code.kx.com/q4m3/0_Overview/
- alyandon 1y agoI just tried to install the community edition and it fails claiming the license key generated by the site is invalid. Not a great onboarding experience.
- steveBK123 1y agodo you have a previous community edition installed? I ran into this than scanned up and saw some warnings about clearing your environment vars & re-sourcing your profile so it no longer points to the old QLIC/QHOME
- tech_advocate 1y agoIf you email preview@kx.com with the details, the team can help resolve the issue and get you up and running.
- optymizer 1y agoWhat a confusing website. The website is named 'defcon', like the famous defense conference. What does 'defcon' have to do with Q? What even is Q? The landing page is uninformative. No explanation of what Q is. References ticks, doesn't mention what these are. The About page is filled with generic words and no substance - so much fluff. I couldn't tell if KDB-X is an exploit database for Defcon participants, or some other kind of specialized database, and at this point I'm so disappointed by this presentation that I lost interest in whatever this piece of software is or does. Luckily someone else on HN figured it out and commented with a TLDR, but I'd use this site as an example of how not to design websites.
- papercrane 1y ago> The website is named 'defcon', like the famous defense conference. Both the defense conference and this are references to the military term DEFCON, that stands for "defense readiness condition". Q here is referring to the Q programming language that is built on top of KDB's K language. The website is a blog and learning resource for the Q language.
- AUnterrainer 1y agoThanks. Looks like at least someone could follow my thought process
- optymizer 1y agoIf your site requires people to explain your thought process, your presentation has failed, unless your goal is to confuse as many visitors as possible, in which case I wouldn't change a thing.
- kristjansson 1y agoIt’s a pretty terrible secondary source, BUT The topic is clearly of interest to the community, and isn’t half the fun of HN learning about things other people are interested in, from the sources they deem acceptable? Why would you only want to read things that are immediately and totally legible to you, specifically?

- mianos 1y agoJust adding, this is completely the opposite to what the original blogspam article says. I think the references to the "Poisoned Chalice", should be updated to replace Macbeth with KX. The promise, (and delivery) of a hyper efficient way to analyse data that kdb/q gives you will always lead to final regret.
- Quitschquat 1y agoWhat would be the closest open-source equivalent for this? Influx?
- secwang 1y agoklongpy
- AUnterrainer 1y agoThere's nothing that gets close to KDB. You can build an entire framework with just KDB
- alt187 1y agoOP cleverly avoided your question by hallucinating one about what could be done with KBD, but yeah. Influx is basically the same niche.
- supercoco9 1y agoQuestDB. It is built for finance workloads (can be also used for other timeseries data, like energy, or aerospace, but has heavy optimizations for common finance data patterns), it is very performant, it has been in used for years at large finance entities, and it is Apache 2.0. Full disclosure: I am a Developer Advocate at QuestDB. The Open Source edition does not limit any commercial use or the size of the machine you can install, as per the Apache 2.0 license terms. If you want more enterprise-y options, like single sign on, or RBAC, there is an Enterprise edition. But Open Source is as performant as the Enterprise version. Enterprise offers also things like replication and TLS on all endpoints, which can be somehow replicated in Open Source with manual sharding or proxies.
- antmarch 1y agoQuestDB does not even support nanosecond, not quite suitable for financial funds
- AUnterrainer 1y agoQuestDB is just a DB. What people get wrong about KDB is that it's so much more. It's a programming language with DB capabilities. You can use for real time streaming, in memory DB and on disk DB. You can build your entire analytics on top of that. There's nothing else out there that let's you build and entire framework/platform with just one single tech stack.
- anthk 1y agoFree as in freedoom? Still not. So, klong for prototyping, and a libre build of 'j' for everything else.
- unit149 1y ago[dead]
- clausok 1y agoKx released a 32bit, free-for-commercial-use version in 2014 and then reversed course around a year later after banks and hedge funds surprised them by flocking to it for a large subset of their developers / dev machines. Hopefully they stick to it this time around. It's an incredible system. It's the only thing I've ever used, including Pandas, dplyr & Matlab, where someone could stand over my shoulder asking data analysis questions and I could answer them, on the fly. LLM's, though notoriously bad (so far) at KDB+/Q compared to other languages, are still a godsend for folks getting started. I recently returned to writing Q after being away from it for 8 years and I've been amazed how good even Google's AI suggestions have been at helping with functions & queries. Getting started tip: try using Q strictly as a query language, avoid K. Do everything else (data shoveling, devops,...) with a different language.
- 0cf8612b2e1e 1y agoCould you give an example of where it shines? I have had to answer many a SQL/pandas question with someone over my shoulder, so curious where you see the sharpest benefit. Admittedly, I am unlikely to learn this proprietary DSL, but always good to know what is the best tool for a job.
- AUnterrainer 1y agoQ is not just a query language or a database. It's an array programming language with database capability. You can build an entire framework with just Q, from real-time streaming, to in memory database to on disk database. You can build all APIs and business logic around it. Because it's vector oriented and in memory it's faster than pretty much everything else, no loops required. I have seen a team of 15 KDB developers build what would require an entire etrading department of 200+ developers
- leprechaun1066 1y agoGiven Wes McKinney created Pandas for quantitative analysis, it's possible that Pandas wouldn't exist if AQR were paying for a q license.
- unixhero 1y agoWhat is the threshold before having to buy a commercial license?
- AUnterrainer 1y agoFor everyone who is still convinced that the community edition isn't free (forever). You can rewatch the Q&A with KX here https://streamyard.com/watch/RGMjB6mdK4eg https://streamyard.com/watch/RGMjB6mdK4eg Sincerely Yours terrible secondary source with a confusing website
