It runs the tests described in ''Performance Evaluation'', Section 7 of the [http://labs.google.com/papers/bigtable.html BigTable paper]. See the citation for test descriptions. They will not be described below. The script is useful evaluating HBase performance and how well it scales as we add region servers. @@ -64, +69 @@ }}} + [[Anchor(first_test)]] == One Region Server on June 8th, 2007 == - Here are some first figures for HBase in advance of any profiling taken June 8, 2007 + Here are some first figures for HBase in advance of any profiling and before addition of caching, etc., taken June 8, 2007 This first test ran on a mini test cluster of four machines only: not the 1768 of the !BigTable paper. Each node had 8G of RAM and 2x dual-core 2Ghz Opterons. Every member ran a HDFS datanode. One node ran the namenode and the HBase master, another the region server and a third an instance of the !PerformanceEvaluation script configured to run one client. Clients write ~1GB of data: One million rows, each row has a single column whose value is 1000 randomly-generated bytes (See the BigTable paper for a better description).
