> 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.
