Method and system for optimizing access to data nodes of a data cluster using a data access gateway and metadata mapping-based bidding

摘要

A method that is performed to access data nodes of a data cluster. The procedure involves receiving a request from a host through a data access gateway (DAG);and in response to the request to receive bid counters from the data nodes; obtaining metadata images from the data nodes; Identify a data node of the data nodes associated with a highest bid counter of the bid counters and a suitable metadata image of the metadata images, based on the bid counters and metadata images; and sending the request to the data node.
