Implementation of stream algebra over class instances

A system for processing high-volume continuous streams of data while maintaining minimal state information associated with the data, said system comprising:

• a memory area for storing a plurality of stream algebra operators for building a distributed stream processing operator graph, each of said stream algebra operators being adapted to perform one or more functions on data events from an event stream;
• and
• a processor configured to execute computer-executable instructions for building a distributed operator graph using the stream algebra operators stored in the memory area by:
• defining an object to include an expression, said expression representing the one or more functions to be performed on the data events from the event stream;
• serializing the defined object including the expression into a message corresponding to one of the plurality of stream algebra operators stored in the memory area;
• identifying one of a plurality of destination computing devices to host said one of the plurality of stream algebra operators;
• transmitting the message to the identified destination computing device to build the distributed operator graph, wherein the destination computing device compiles the expression from the message into executable code representing said one of the plurality of stream algebra operators implementing a portion of the operator graph, wherein the executable code operates on the data events received from the event stream to produce aggregated events;
• receiving the aggregated events from the destination computing device;
• and
• processing the aggregated events in accordance with another portion of the operator graph implemented by the processor.

A method for configuring an operator graph to process a continuous stream of events, said method comprising:

• defining an object to include an expression, said expression representing a function to be performed on events from an event stream;
• generating an abstract syntax tree corresponding to the object;
• serializing the generated abstract syntax tree into a message;
• and
• sending the message representing the object to a destination machine, said destination machine being one of a plurality of machines, wherein the destination machine compiles the expression from the abstract syntax tree into executable code, wherein the executable code is executed on events received from the event stream.
