Abstract
Exemplary embodiments provide a hybrid buffer pool for a database that includes a plurality of data pages contained in storage. The hybrid buffer pool comprises: a shared buffer pool of page frames containing dirty data pages that are modified after reading that will be written back to storage; an immutable buffer pool that temporarily contains read-only data pages from the storage; and a page multiplexer that identifies which ones of the data pages from storage to store in the immutable buffer pool based at least in part on information from a query processor.
