Wire external source splits into the data node execution path so that distributed Parquet (and similar) reads fan out to data nodes instead of running only on the coordinator. - DataNodeRequest: carry ExternalSplit list with TransportVersion guard - ComputeService: ExternalDistributionResult, executeExternalDistribution - DataNodeComputeHandler: startExternalComputeOnDataNodes, handleExternalSourceRequest - PlannerUtils: localPlan overload accepting SearchStats + FilterPushdownRegistry - TransportEsqlQueryAction: wire FilterPushdownRegistry into ComputeService - ExternalSourceDataNodeTests: unit tests for distribution and split injection Developed using AI-assisted tooling
