Subject [Hadoop Wiki] Update of "Hbase/PoweredBy" by Ferdy
Date Thu, 07 Jan 2010 09:34:42 GMT
Dear Wiki user,

You have subscribed to a wiki page or wiki category on "Hadoop Wiki" for change notification.

The "Hbase/PoweredBy" page has been changed by Ferdy.


  [[http://www.flurry.com|Flurry]] provides mobile application analytics.  We use HBase and
Hadoop for all of our analytics processing, and serve all of our live requests directly out
of HBase on our 16-node production cluster with billions of rows over several tables.
  [[http://www.drawntoscaleconsulting.com|Drawn to Scale Consulting]] consults on HBase, Hadoop,
Distributed Search, and Scalable architectures.
+ [[http://www.kalooga.com|Kalooga]] is a discovery service for image galleries. We use Hadoop,
Hbase, Chukwa and Pig on a 20-node cluster for our crawling, analysis and events processing.
  [[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.
