摘要: A method and apparatus is provided for dynamically generating data to dataset mappings and dataset to logical instance mappings and distributing these mappings to subscribers for the purpose of routing work. An advisory engine updates the mappings of data to data sets based at least in part on changing demands and patterns of access to data, and updates the mappings of datasets to logical instances based at least in part on anticipated capacity and change in conditions of the database servers. The subscribers receive and store the mapping information that maps the data to dataset identifiers, and dataset identifiers to logical database instances. The subscribers may also receive information that describes the current availability conditions of database instances, which are used to override the mapping of logical database instances to physical database instances. Subscribers may use the data to dataset mapping to map data identified from in an incoming database request to a dataset. Subscribers may use the dataset to logical instance mapping to map a dataset to a possible database server, and the logical instance to physical instance mapping to map a possible database server to an available database server. In this manner, the subscribers may route data efficiently even when access patterns and server conditions change.
