Isolating Resources and Performance in a Database Management System

摘要

Techniques for tenant performance isolation in a multiple-tenant database management system are described. These techniques may include providing a reservation of server resources. The server resources reservation may include a reservation of a central processing unit (CPU), a reservation of Input/Output throughput, and/or a reservation of buffer pool memory or working memory. The techniques may also include a metering mechanism that determines whether the resource reservation is satisfied. The metering mechanism may be independent of an actual resource allocation mechanism associated with the server resource reservation.

1. A computer-implemented method comprising:
providing, in a database server process, a reservation of one or more server resources for a tenant, the one or more server resources including at least one of a central processing unit (CPU), memory, and an Input/Output (I/O) throughput associated with a server; and metering the reservation to determine whether the reservation for the tenant is met.
