Abstract
Provided are systems and methods for paging data into main memory from checkpoint data stored on disk. In one example, the method may include one or more of receiving a request for a database record in main memory, determining whether the database record has been previously stored in the main memory, in response to determining that the database record has been previously stored in the main memory, identifying a slice where the database record was stored from among a plurality of slices included in the main memory, and paging content of the identified slice including a copy of the requested database record into the main memory from a snapshot captured of content included in the identified slice and previously stored on disk. Accordingly, documents can be paged into main memory on-demand from snapshots of slice content rather than paging an entire partition of content.
