Abstract
Compact hosting of database query processors is performed using virtualization snapshots. When a request to access a database is received via a previously established connection from a client for an idle query processor that is not currently executing, a virtualization snapshot may be identified that is associated with the idle query processor. The virtualization snapshot of the query processor may be used to restore the query processor into virtual execution on a host system for the database using an origin snapshot that shares clean pages across multiple query processors on the host system. The request may be performed by the restored query processor in virtual execution on the host system.
