摘要：HYRISE is a new relational storage engine for main memory database systems. It is built on the premise
that enterprise application workloads can benefit from a dedicated main-memory storage engine. The
key idea behind HYRISE is that it provides dynamic vertical partitioning of the tables it stores. Since
enterprise applications typically use a large number of very wide tables, we designed a novel layout
algorithm specifically tailored for enterprise data. Our algorithm uses a main memory cost model that
is able to precisely estimate the physical access cost of database operators and to determine a vertical
partitioning that yields the best execution performance.
