FamilySearch, owned by the Church of Jesus Christ of Latter-day Saints, is one of the largest web properties in the family history industry holding over 3 billion vital records and images used to help patrons in discovering their roots. Only the social network Facebook rivals it for sheer amount of data it must parse and serve: The social graph, or lineage graph in this case, poses a very significant Big Data challenge. FamilySearch is curating the family history of mankind, and holds approximately one billion records in a lineage-linked “tree of mankind.” This session will outline why FamilySearch is moving off traditional relational database technology to tackle its family history Big Data problems, and will include a discussion of its process for evaluating MongoDB to significantly increase both the performance and scale of its family tree application. It will also feature an early demonstration of a special “Bumping” application that allows two users to locate where their family trees may have linked up generations ago.
