More Information
Summary:Performing a distributed database transaction using parallel writes to a distributed append-only database system is provided. A central database and a plurality of distributed databases, also known as "shards", may be used. A request made to implement a distributed transaction, requiring updates to one or more shards, results in a monotonically increasing identification (ID) number being assigned to a change set. The request and change set may be registered at the central database. Once the change set is completely written to all of the appropriate shards, the change set is marked as completed in the central database. After write completion, a change set ID boundary at the central database is advanced to indicate the current fully changed status of the distributed database.
