The fastest time-series database, we have used. The different types of join are very useful, once you learn ALL of them and their nuances.

SK Shatrughan K. KDB Trainer Enterprise (\> 1000 emp.) 7/23/2023 "Speed, Scalable & Succinct" 4.5/5 What do you like best about KX? The terseness of Q language has won me. So much could be done in so less is amazing about KDB/q. Even the whole application is only few KBs and that contains whole world of analytical functions with well thought implementation to work on huge dataset in a jiffy. It's highly recommended for the scalable timeseries data specially for huge volumes where lot of analysis is involved and speed is the key. Review collected by and hosted on G2.com. What do you dislike about KX? Though I have seen the documentation and online helps improving over last one decade, as compared to other traditional databases and languages, there is still a significant gap. Moreover, for many years, it has been a closed community with not much documents in public domain. But now, it's no more the same. There are a lot of forums and helps available. Review collected by and hosted on G2.com. What problems is KX solving and how is that benefiting you? Storing the trading data and providing analytics on the data. I have used it as a KDB developer in several investment banks. It certainly gave results real quick in comparison to all other databases for the same amount of data.
