Our application is a web crawling application with concurrent batch content analysis of various kinds. All of the workflow components are implemented as subclasses of !TableMap and/or !TableReduce on a cluster of 25 nodes. We see a constant rate of 2500 requests/sec or greater, peaking periodically near 100K/sec when some of the batch scan tasks run. + [http://www.veoh.com/ 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. + [http://www.videosurf.com/ 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 it's column-oriented nature allowed us to create schemas that were substantially more efficient for storing and retrieving data.
