real-time search infrastructure and architecture at craigslist

Handling hundreds of millions of search queries per day against a data set that normally lives in MySQL and is constantly changing and growing presents a number of interesting challenges.  Things get even more fun when you'd like to move from "batch updates" of your search indexes to real-time.  That's what we've done at craigslist in the last year using the open source Sphinx search engine along with MySQL and some custom Perl code to tie it all together.

This presentation will include:
• a brief overview of the sphinx search engine and why we use it
• a snapshot of our previous search architecture(s)
• our new search architecture
• lessons learned and pain points along the way
• new sphinx features that make real-time indexing more flexible
• ideas for future enhancements

    I just now changed my meetup profile name to exactly match my photo id (Lee Melton). Prior to 5 mins ago my meetup profile name showed the nickname I go by (Buck Melton). Hopefully this is not a problem.
