NETWORK-INDEPENDENT PROGRAMMING MODEL FOR ONLINE PROCESSING IN DISTRIBUTED SYSTEMS

Systems and methods include a distributed system that uses a declarative language to separate application logic from the network technology used to communicate. For example, in a system with a plurality of processing nodes, each processing node may include at least one processor, a networking layer for communicating with other processing nodes, and a memory storing instructions that, when executed by the at least one processor, cause the processing node to perform operations. The operations may include receiving a processing plan using the networking layer and analyzing the processing plan to determine a service to perform and a number of inputs anticipated for the service. The operations may also include performing the determined service. The processing plan defines a processing tree comprising a subset of the plurality of processing nodes, the processing tree having unidirectional communication from the root to a final level of the tree.
