Abstract: Embodiments are disclosed for a method. The method includes receiving a plurality of local deltas for a query execution against a corresponding plurality of data sources hosted by a corresponding plurality of distributed nodes of a dynamic distributed network. The method also includes generating a combined delta by combining the local deltas. Additionally, the method includes generating a determined delta result by performing additional processing on the combined delta. Further, the method includes providing the determined delta for one of the distributed nodes.

Abstract: Embodiments are disclosed for a method. The method includes parsing a distributed database query into component queries corresponding to distributed nodes. The method also includes matching component queries to central cache to determine whether the component queries can be satisfied. This matching generates matched and unmatched component queries. The method further includes transforming the matched component query to a cache query and local delta query for a first node. Additionally, the method includes executing the cache query to generate a cache result. Also, the method includes providing the local delta query for the first node to generate a local delta. Further, the method includes providing the unmatched component query for a second node to generate a remote result. The method also includes generating a global delta based on the local delta. The method additionally includes generating a result by combining the cache result, local delta, and remote result.
