+    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 -

+  <dd>Runa Inc. offers a SaaS that enables online merchants to offer dynamic

+    this we collect the click streams of all their visitors to determine along
+    with the rules of the merchant what promotion to offer the visitor at different
+    points of their browsing the Merchant website. So we have lots of data and have
+    to do lots of off-line and real-time analytics. HBase is the core for us.
+    We also use Clojure and our own open sourced distributed processing framework,
+    Swarmiji. The HBase Community has been key to our forward movement with HBase.

+  <dd>SocialMedia uses HBase to store and process user events which allows us to

+  <dd>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

+    in MySQL.</dd>
+
+  <dt><a href=">http://www.tokenizer.org">Shopping Engine at Tokenizer</a></dt>
+  <dd>Shopping Engine at Tokenizer is a web crawler; it uses HBase to store URLs
+    and Outlinks (AnchorText + LinkedURL): more than a billion. It was initially
+    designed as Nutch-Hadoop extension, then (due to very specific 'shopping'
+    scenario) moved to SOLR + MySQL(InnoDB) (ten thousands queries per second),
+    and now - to HBase. HBase is significantly faster due to: no need for huge
+    transaction logs, column-oriented design exactly matches 'lazy' business logic,
+    data compression, !MapReduce support. Number of mutable 'indexes' (term from
+    RDBMS) significantly reduced due to the fact that each 'row::column' structure
+    is physically sorted by 'row'. MySQL InnoDB engine is best DB choice for
+    highly-concurrent updates. However, necessity to flash a block of data to
+    harddrive even if we changed only few bytes is obvious bottleneck. HBase
+    greatly helps: not-so-popular in modern DBMS 'delete-insert', 'mutable primary
+    key', and 'natural primary key' patterns become a big advantage with HBase.</dd>
+
+  <dt><a href="http://traackr.com/">Traackr</a></dt>
+  <dd>Traackr uses HBase to store and serve online influencer data in real-time.

+
+  <dt><a href="http://trendmicro.com/">Trend Micro</a></dt>
+  <dd>Trend Micro uses HBase as a foundation for cloud scale storage for a variety

+    production since version 0.20.0.</dd>
+
+  <dt><a href="http://www.twitter.com">Twitter</a></dt>
+  <dd>Twitter runs HBase across its entire Hadoop cluster. HBase provides a
+    distributed, read/write backup of all  mysql tables in Twitter's production
+    backend, allowing engineers to run MapReduce jobs over the data while maintaining
+    the ability to apply periodic row updates (something that is more difficult
+    to do with vanilla HDFS).  A number of applications including people search
+    rely on HBase internally for data generation. Additionally, the operations
+    team uses HBase as a timeseries database for cluster-wide monitoring/performance
+    data.</dd>
+
+  <dt><a href="http://www.udanax.org">Udanax.org</a></dt>
+  <dd>Udanax.org is a URL shortener which use 10 nodes HBase cluster to store URLs,
+    Web Log data and response the real-time request on its Web Server. This
+    application is now used for some twitter clients and a number of web sites.
+    Currently API requests are almost 30 per second and web redirection requests
+    are about 300 per second.</dd>
+
+  <dt><a href="http://www.veoh.com/">Veoh Networks</a></dt>
+  <dd>Veoh Networks uses HBase to store and process visitor (human) and entity
+    (non-human) profiles which are used for behavioral targeting, demographic
+    detection, and personalization services.  Our site reads this data in
+    real-time (heavily cached) and submits updates via various batch map/reduce
+    jobs. With 25 million unique visitors a month storing this data in a traditional
+    RDBMS is not an option. We currently have a 24 node Hadoop/HBase cluster and
+    our profiling system is sharing this cluster with our other Hadoop data
+    pipeline processes.</dd>
+
+  <dt><a href="http://www.videosurf.com/">VideoSurf</a></dt>
+  <dd>VideoSurf - "The video search engine that has taught computers to see".
+    We're using HBase to persist various large graphs of data and other statistics.
+    HBase was a real win for us because it let us store substantially larger
+    datasets without the need for manually partitioning the data and its
+    column-oriented nature allowed us to create schemas that were substantially
+    more efficient for storing and retrieving data.</dd>
+
+  <dt><a href="http://www.visibletechnologies.com/">Visible Technologies</a></dt>
+  <dd>Visible Technologies uses Hadoop, HBase, Katta, and more to collect, parse,
+    store, and search hundreds of millions of Social Media content. We get incredibly
+    fast throughput and very low latency on commodity hardware. HBase enables our
+    business to exist.</dd>
+
+  <dt><a href="http://www.worldlingo.com/">WorldLingo</a></dt>
+  <dd>The WorldLingo Multilingual Archive. We use HBase to store millions of
+    documents that we scan using Map/Reduce jobs to machine translate them into
+    all or selected target languages from our set of available machine translation
+    languages. We currently store 12 million documents but plan to eventually
+    reach the 450 million mark. HBase allows us to scale out as we need to grow
+    our storage capacities. Combined with Hadoop to keep the data replicated and
+    therefore fail-safe we have the backbone our service can rely on now and in
+    the future. !WorldLingo is using HBase since December 2007 and is along with
+    a few others one of the longest running HBase installation. Currently we are
+    running the latest HBase 0.20 and serving directly from it at

+  <dd>Yahoo! uses HBase to store document fingerprint for detecting near-duplications.
