title: Lambda architecture - what is origin of this name?
body: <p>I've read Manning's Big Data Lambda Architecture (<a href="http://www.manning.com/marz/BD_meap_ch01.pdf" rel="noreferrer">http://www.manning.com/marz/BD_meap_ch01.pdf</a>) and still not able to get why it's named 'Lambda'. Is it kinda code-name or name of system this architecture is based on?</p>
