Database session dependent routing

A network device, comprising:

• a processing unit configured to:
• issue a session globally unique identifier (GUID) to an application for use in a database read/write session,
• determine a session key based on the session GUID;
• determine a total number of database nodes available to handle a read/write session with the application, and
• determine one of the database nodes to route a session to based on applying a modulo operation to the session key and to the determined total number of available database nodes.

A tangible non-transitory computer-readable medium containing instructions executable by at least one processor, the tangible non-transitory computer-readable medium comprising:

• one or more instructions for issuing a session globally unique identifier (GUID) to an application for use in a database read/write session;
• one or more instructions for determining a session key based on the GUID;
• one or more instructions for determining a total number of database nodes available to handle a read/write session with the application, and
• one or more instructions for determining 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 tangible non-transitory computer-readable medium of 15, wherein the one or more instructions for determining the one of the database nodes to route a session to further comprise:

• one or more instructions for applying the function (X mod Y)+1,
• wherein X is the session key,
• Y is the total number of available database nodes, and
• mod is a modulo function that determines a remainder of a division of the session key (X) by the total number (Y) of available DB nodes.
