SYSTEMS AND METHODS FOR TUNING MULTI-STORE SYSTEMS TO SPEED UP BIG DATA QUERY WORKLOAD |
摘要 |
Systems and methods are disclosed to run a multistore system by receiving by-products of query processing in the multistore system, wherein the by-products include views or materializations of intermediate data; placing the views or materializations across the stores based on recently observed queries as indicative of a future query workload; determining a benefit score for each view based on a predicted future query workload, wherein each store has an allotted view storage budget, and there is a view transfer budget for transferring views between the stores; and tuning a physical design of the multistore system. |
