Roadblock title:

Finding a PAN in a haystack: An efficient algorithm for sub-millisecond lookups

Time:

Friday - 10:00 AM (5th floor - Manchester G)

Abstract:

Join Adam on a journey of how his team achieved sub-millisecond op times to check if a PAN exists in a range containing 69 trillion account numbers on average. In this presentation, we will iterate from big dataset to data store to caching to lookup algorithm.

While that problem might seem straightforward, challenges arose with 21-digit numbers exceeding 64-bit integer limits, causing slow queries. Meanwhile, we also dealt with curve balls that a modern scalable software architecture can throw at the unexpecting engineer.

My presentation aims to celebrate solving hard problems with simple solutions that is ultimately what the craft of software engineering is all about. The takeaway for the audience is that an often overlooked tool in the software engineer toolkit is to keep the solution simple.
