q is the programming language underpinning kdb+ by Kx Systems - often claimed (by Kx) to be "the fastest database in the world". Possibly also the most expensive? L is an independent implementation of a q interpreter. To those who reluctantly commercially license kdb+ - this will be a welcome alternative.
Absolutely and given Kx is now private equity owned and are in the customer-squeezing phase of the acquisition, this is very welcome indeed.
