Abstract
A fine-grained scalable time-versioning support for large-scale property graph databases includes receiving a request, wherein the request includes an entity identifier (ID) and reference time information, and searching entries of a first table using the entity ID as a first key. Matching an entry is performed corresponding to the first key in the first table, determining the entry is valid based at least in part on comparing the reference time information of the request with stored time information for the entry, and responsive to the determination, creating a second key, wherein the second key concatenates an ID associated with the entity ID with the reference time information of the request. Searching a second table is performed having entries based at least in part on the second key, and responsive to searching the second table, retrieving data associated with the second key.
