Abstract: A data engine request is received on a local data system. The data engine request includes a portion of the request that is to be processed on an external data engine system. The portion is forwarded to the external data engine system and statistics for accessing external objects of the external data engine system is acquired. The statistics are evaluated for compliance with a Service Level Goal (SLG) associated with the request. Rules-based processing permits optimization and planning of the request on the local data engine system to be modified in view of the statistics received from the external data engine system to comply with the SLG. In an embodiment, actual resource utilization metrics noted during execution of the portion on the external data engine system is provided as feedback to the local data engine system for re-planning and re-optimizing the request with a modified execution plan.
