Kx offers a 32-bit version of kdb+ for free so you can try it for yourself and see how powerful and fast it is. This version has all the functionality of the full 64-bit version and is for non-commercial use only. This software may not be used in production systems. Kx does not provide technical support.
32-bit kdb+ can only be used in a commercial environment for proof of concept applications, development, and in cases where permission is explicitly granted by Kx. Please contact us at firstname.lastname@example.org if you are a current customer who would like to use 32-bit kdb+ in a production application.
