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 RichReimer:

  [[http://www.socialmedia.com/|SocialMedia]] uses HBase to store and process user events
which allows us to provide near-realtime user metrics and reporting. HBase forms the heart
of our Advertising Network data storage and management system. We use HBase as a data source
and sink for both realtime request cycle queries and as a backend for mapreduce analysis.
  
- [[http://www.splicemachine.com/|Splice Machine]] built the Splice SQL Engine on top of HBase.
 The Splice SQL Engine is a full-featured ANSI SQL database that provides real-time updates,
secondary indices, ACID transactions, and optimized joins.

is a full-featured ANSI SQL database that provides real-time updates, secondary indices, ACID
transactions, optimized joins, triggers, and UDFs.
  
  [[http://www.streamy.com/|Streamy]] is a recently launched realtime social news site.  We
use HBase for all of our data storage, query, and analysis needs, replacing an existing SQL-based
system.  This includes hundreds of millions of documents, sparse matrices, logs, and everything
else once done in the relational system.  We perform significant in-memory caching of query
results similar to a traditional Memcached/SQL setup as well as other external components
to perform joining and sorting.  We also run thousands of daily MapReduce jobs using HBase
tables for log analysis, attention data processing, and feed crawling.  HBase has helped us
scale and distribute in ways we could not otherwise, and the community has provided consistent
and invaluable assistance.
