System and method for adaptive filtering of data requests

This disclosure describes systems and methods related to filtering data requests. In some embodiments, a system may determine an execution plan tree. The system may determine a backend-processed target table in the at least one first storage device. The system may traverse at least one first branch and at least one first node in the execution plan tree. The system may traverse at least one second branch and at least one second node from the parent join node. The system may determine that the rowsource is referenced at the rowsource-access node. The system may determine that the rowsource referenced at the rowsource-access node is a filtered-rowsource. The system may extract at least one join column from a join condition associated with the backend-processed target table and the filtered-rowsource. The system may determine at least one storage location of the filtered-rowsource. The system may determine an adaptive processing path based at least in part on the at least one storage location of the filtered-rowsource, the at least one join column determined from the join condition and the at least one direct predicate determined for the filtered-rowsource. The system may generate at least one target filter predicate for the backend-processed target table.
