At 1.6 Billion Queries Per Day, Twitter Finally Aims To Make Search Personally Relevant

While much of the talk leading up to today was about Twitter's move into the photo game, the bigger news is actually what they've done to their search product. They've completely rebuilt it. And while it may not be immediately apparent, the product should be much, much better than before. Twitter details the project in a long post on their Engineering blog today. Notably, they go into the backstory of Twitter Search, which evolved from the Summize purchase in 2008. While that product worked well for a while, the technologies behind it would not allow it to scale to the level that Twitter eventually needed. So things had to be re-written ? on the fly. Twitter detailed some of this last October.�But it wasn't until this past April that they were able to replace the old Ruby on Rails front-end with the newly-built Blender. At the time, Twitter said this made search 3x faster and gave them 10x throughput. This is important since they're now seeing 2,200 tweets-per-second on average and serving up 18,000 queries per second ? 1.6 billion queries per day. That's up from 1 billion last Ocotober.
