1. A system comprising:
a plurality of processors, wherein each processor of the plurality of processors is dedicated to receive one or more of a plurality of input topic streams;
a plurality of stream stores for storing data, wherein each stream store of the plurality of stream stores is dedicated to store one or more of the plurality of input topic streams; and
a route processor in communication with each of the plurality of stream stores;
wherein the route processor determines whether a route for a network topology corresponds with an existing route stored on at least one of the plurality of stream stores;
wherein the route processor is configured to execute instructions for tracking prefixes within a network topology based on telemetry data;
wherein the instructions comprise:
receiving a route for the network topology by way of a route stream of the plurality of input topic streams; and
determining whether the route corresponds with an existing route stored on a route store of the plurality of stream stores; and
wherein the instructions further comprise:
in response to determining the route corresponds with the existing route, determining whether any network routing paths have been modified between the existing route and the route; and
in response to determining at least one network routing path was modified between the existing route and the route, generating a path configuration key for each of the at least one network routing path.
