The following page has been changed by GaryHelmling: http://wiki.apache.org/hadoop/Hbase/PoweredBy ------------------------------------------------------------------------------ [http://gumgum.com GumGum] is an analytics and monetization platform for online content. We've developed usage-based licensing models that make the best content in the world accessible to publishers of all sizes. We use HBase 0.20.0 on a 4-node Amazon EC2 cluster to record visits to advertisers in our ad network. Our production cluster has been running since July 2009. [http://www.mahalo.com Mahalo], "...the world's first human-powered search engine". All the markup that powers the wiki is stored in HBase. It's been in use for a few months now. !MediaWiki - the same software that power Wikipedia - has version/revision control. Mahalo's in-house editors produce a lot of revisions per day, which was not working well in a RDBMS. An hbase-based solution for this was built and tested, and the data migrated out of MySQL and into HBase. Right now it's at something like 6 million items in HBase. The upload tool runs every hour from a shell script to back up that data, and on 6 nodes takes about 5-10 minutes to run - and does not slow down production at all. + + [http://www.meetup.com Meetup] is on a mission to help the worldâs people self-organize into local groups. We use Hadoop and HBase to power a site-wide, real-time activity feed system for all of our members and groups. Group activity is written directly to HBase, and indexed per member, with the member's custom feed served directly from HBase for incoming requests. We're running HBase 0.20.0 on a 11 node cluster. [http://www.openplaces.org Openplaces] is a search engine for travel that uses HBase to store terabytes of web pages and travel-related entity records (countries, cities, hotels, etc.). We have dozens of MapReduce jobs that crunch data on a daily basis. We use a 20-node cluster for development, a 40-node cluster for offline production processing and an EC2 cluster for the live web site.
