A network device issues a globally unique identifier (GUID) to an application for use in a database read/write session. The network device determines a session key based on the GUID. The network device determines a total number of database nodes available to handle a read/write session with the application, and determines one of the database nodes to route a session to based on applying a modulo function to the session key and to the determined total number of database nodes. The network device, when determining the one of the database nodes to route the session to, applies the function (X mod Y)+1, where X is the session key and Y is the total number of database nodes available to handle the read/write session with the application.
