摘要： A database system for processing a query includes at least one master node that is operable to communicate a multicast signal over a plurality of communication channels. The multicast signal includes a request to perform an action associated with a pre-compiled query. In one particular embodiment, the at least one master node communicates the multicast signal over a first communication channel. The system also includes a plurality of slave nodes that are coupled to the at least one master node. Each of the plurality of slave nodes is operable to receive the multicast signal from the first communication channel. In this particular embodiment, at least one of the plurality of slave nodes provides access to at least one key part that is also accessible through another one of the plurality of slave nodes.

摘要： A database system that is capable of using an activity ID for processing a query. The database system includes at least one master node that is operable to communicate a request to perform a remote action associated with a pre-compiled query. The request comprises an activity ID that identifies the remote action associated with the pre-compiled query. The system further includes at least one slave node that is coupled to the at least one master node. The at least one slave node is operable to receive the request to perform the remote action and to process the request to perform the remote action. In one particular embodiment, the activity ID operates to directs the at least one slave node to one or more executables for use in processing the request.

摘要： A database system for processing a query request comprises a master node that communicates a request to perform one or more activities associated with a precompiled query over at least one communication channel. A plurality of slave nodes are coupled to the master node. At least a particular one of the slave node receives the request communicated by the master node, performs at least a portion of the one or more activities associated with the request to obtain one or more results for the request, communicates a request-to-send message to the master node indicating that the one or more results are available for communication to the master node, and communicates at least a portion of the one or more results to the master node in response to receiving a permission-to-send message from the master node.
