A cluster of small (wimpy) servers, where the number of nodes can dynamically adjust to the current workload, might offer better energy characteristics for these workloads. ...
Traditional DBMS servers are usually over-provisioned for most of their daily workloads and, because they do not show good energy proportionality, waste a lot of energy while underutilized. ...
Therefore, the query plan for transactional workloads is much more rigid than OLAP queries. In summary, it is comprehensible, that a cluster of nodes is better suited for OLAP workloads than OLTP. ...
