Abstract
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.
