Abstract
The present invention extends to methods, systems, computer program products, and data structures for managing database snapshot storage. Spatial properties database transactions are used to manage database snapshot storage allocation and reclamation. When a read transaction and subsequent write transactions refer to disjoint portions of a database, the read transaction can continue to read portions of data directly from the database. When a read transaction and subsequent write transactions refer to intersecting portions of a database, the read transaction can be transitioned to 'snapshot' mode. The write transaction can publish a database snapshot can configure the read transaction to read contested portions of data from the published snapshot.
