Reduction of message flow between bus-connected consumers and producers

摘要

A system, method, and computer readable medium for reducing message flow on a message bus are disclosed. The method includes determining if at least one logical operator in a plurality of logical operators requires processing on a given physical processing node in a group of physical nodes. The logical operator is pinned to the given physical processing node. The pinning prevents any subsequent reassignment of the logical operator to another physical processing node. Each logical operator in the plurality of logical operators is assigned to an initial physical processing node in the group of physical processing nodes on a message bus. A determination is made as to whether at least one logical operating in the plurality of logical operators needs to be reassigned to a different physical processing node. The at least one logical operator is reassigned to the different physical processing node.
