Provided herein are systems and methods for hash-join broadcast decision making. For example, a method includes generating a query plan for a received query. The query plan includes a plurality of join operations with a plurality of hash-join-build (HJB) operations and a plurality of hash-join-probe (HJP) operations. A decision node of a plurality of decision nodes of the query plan is configured as a primary decision node. Build-side data information associated with build-side data and received from the plurality of HJB operations is decoded by the primary decision node. A data distribution method is determined by the primary decision node for each HJB operation of the plurality of HJB operations based on the build-side data information. The query plan is executed based on distributing the build-side data to the plurality of HJP operations using the data distribution method for each HJB operation of the plurality of HJB operations.
