Looks like Yahoo is open sourcing their Vespa scaled recommendation handling service. Anyone know details on its successes and failures?
Old yahoo here who worked on sports. This reads like the container stuff we used behind yql and then later on yql+ got rebranded. Sports plus fantasy sports served up to 40k requests a second. It is not really AI though. You had to program the queries correctly. This sounds like some crazy branding. Other yahoos wanna chime in?
This is an amazing piece of tech. Extremely well battle tested. Used it for several years. I would recommend it without any qualifications.
We used it for mail search previously
It’s not the best one but it’s definitely a decent one. I work with Sherpa and Vespa and the grid a lot
What is your take on Sherpa?
It destroys elasticsearch for traffic serving and elasticity. ES can’t do shards allocation correctly
I used to work at Yahoo and use it. Been used for more than 10 years internally with the company and has had multiple iterations. Well battle tested.
