Locking is one of the predominant costs in transaction processing. While much work has focused on designing efficient concurrency control mechanisms, not much has been done on understanding how transaction applications issue queries and leveraging application semantics to improve application performance. This paper presents QURO, a query-aware compiler that automatically reorders queries in transaction code to improve performance. Observing that certain queries within a transaction are more… CONTINUE READING
