> Have been running ten concurrent clients uploading wikipedia to hbase.  Each update includes
some metadata -- URL, mimetype -- and the page content.  Caching updates across compactions
and splits, we OOME (Default heap size of 1G).  10 concurrent clients are doing over 10k rows
a minute.  HBase should be able to carry this common loading scenario.
