I think he means they one of the biggest consumers of cluster resources. Each group within google probably has a quota for how many resources they are allowed to use. It's unclear here if their consumption is so huge because they are successful or inefficient though...
- math-dev 5y agoDoes anybody know what they actually do? I see them mentioned all the time but I don’t get it. Is it just flight information or do they do pricing analysis and other stuff
- p_l 5y agoQPX (ITA's, and now Google's) system is responsible for calculating and searching airfares, i.e. the complete "solution" for "I want to get from A to B with those constraints". It's what responds when you ask google flight for a route, essentially. This is quite computationally complex due to many dimensions involved in airfare calculations. This system is essentially implemented on top of SBCL with some small bits of C++ (responsible, IIRC, for handling memory-mapped airfare data files).
