Why kdb+ and not another database? Language?

[admin]

I often get asked why is kdb+ used by banks why not XXXX?
Where XXX is hadoop, mongodb,spark…..

I would turn this around and ask what is your particular goal?
– Take the essential use cases you need
– What criteria does that give us for evaluating a technology stack
– Let’s take into account the skill set of our team
– And the projected Total Cost of Ownership

Then under that criteria let’s see what is the best solution.

We’ve previously posted a comparison of different column oriented databases.

Nowadays I would expand this further to include data stores available in a particular language, data frames in R, pandas in python…

For kdb+ list it’s strengths:

1. Kdb+ the Database – Column Oriented DB allowing fast timeseries analysis
2. q language – fast, interpreted vector based language
3. Combined power of kdb+/q – Change how you think!

Now weight up the pros and cons and decide.
