It’s Official: Google Adds Caffeine to its Brew
Share Tweet
Today Google formally announced on its blog that it has completed its launch of he new indexing system dubbed “caffeine”. Google originally announced the caffeine indexing infrastructure in August of 2009 and then launched a version of it on a single data-center later in the year. Today’s announcement makes it official that caffeine is live on all Google data-centers.
Highlights of the Caffeine Announcement
- The size of the Google index is larger than ever
- Google claims that all search results are 50% fresher meaning that new content being added to the web will appear in search results faster. This does not change the frequency of Google’s indexing of websites, it simply means that new information is pushed live to the index faster than before.
- Storage Capacity Increased Greatly- Google’s caffeine currently requires 100 million gigabytes of storage. (that’s 625,000 of the largest ipods to you and me).
- The primary reasons for the update are to deliver fresher content at a close to real time rate and to create a foundation for the future as the internet grows.
