Abstract
Systems and methods for improving database system performance are described. In one embodiment, a database system includes a master database, a replica database, a shared memory, and a multiplexer coupled to the master database, replica database, and shared memory. The multiplexer is configured to receive a request from a client computing system which includes a database query. Based on a lookup in the shared memory, the multiplexer determines that the database query can be satisfied by the replica database. In response, the database query is routed to the replica database for execution.
