Abstract
One embodiment of the present invention provides a system that speeds up an application by allowing database tables associated with the application to be partitioned across N read-only slave database servers. In this way, each slave database server can process 1/Nth of the workload of the application. Since this processing can take place in parallel, the system can potentially speed up the application by a factor of N. The system includes a master-slave database hierarchy, which includes a plurality of read-only database servers for servicing read operations and a master database server for servicing both read operations and write operations. This master database server contains an entire database and the plurality of read-only database servers contain local read-only copies of portions of the database. The system operates by receiving a database request from an application server at a read-only database server.
