Abstract
A database system includes a rescheduler that performs rescheduling of transactions in a scheduling queue based on one or more criteria. One criterion is whether a first transaction in the queue can be performed as a synchronized scan of a table with a second transaction that is currently executing. This enables the first and second transactions to share a segment of a buffer storage pool.
