Everything operating at Walmart needs to work at scale. Just throwing hardware and cloud-resources at the problem in many cases is not enough.
Event scheduling is one of the situations where we need to add a considerable amount of smarts into the mix. Sandeep Malik has the smarts and experience it takes and he blogged about his solution on our engineering blog.
We are now pleased to announce that the distributed event scheduler BigBen is now open source and available for you all to use and contribute to.
I am sure Sandeep is looking forward to hear about your experience and ready to help you with new features or bug fixes as needed.
Congratulations from the WalmarLabs Open Source Team!
