I am aware of J, but it seems to me that J is comparable to K, not Q&#x2F;KDB+.  If you want a python comparison, then K is python, and Q&#x2F;KDB+ is more like pandas.  Except much, much quicker, and more powerful, but without as many tools and packages to support it.  But that could be fixed - those tools and packages don&#x27;t exist because the community isn&#x27;t there, because it is (sadly) closed source.
