Client-Side Directed Commands to a Loosely Coupled Database

摘要

Dynamically directing a command to a node in a distributed database is described. An example method includes receiving the command from a client application to access data in the distributed database, where the command contains a set of parameters. A primary key is constructed from at least some of the parameters. The client further generates routing information from a node-partition table based on a comparison of the primary key with an entry in the node-partition table, where the node-partition table maps the primary key to a node in the distributed database. Accordingly, the command is directed to the node in the distributed database based on the routing information.

1. A computer-implemented method for dynamically directing a command to a node in a distributed database, comprising:
receiving the command from a client application to access data in the distributed database, wherein the command contains a set of parameters; constructing a primary key from at least some of the parameters; generating routing information from a node-partition table based on a comparison of the primary key with an entry in the node-partition table, wherein the node-partition table maps the primary key to the node in the distributed database; and directing the command to the node in the distributed database based on the routing information.
