Abstract

A query is received and an initial data flow graph comprising a plurality of nodes is generated for executing the query. The initial data flow graph is optimized using a model optimizer that accesses at least one of a plurality of patterns to identify a matching pattern and executes at least one optimization rule associated with a matching pattern. Execution of the query is then initiated using the optimized data flow graph. Related apparatus, systems, techniques and articles are also described.
