Abstract
Architecture that includes an ordered and shared log of indexed transaction records represented as multi-version data structures of nodes and node pointers. The log is a sole monolithic source of datastore state and is used for enforcing concurrency control. The architecture also includes a transaction processing component that appends transaction records to the log from concurrent transactions executing on different processors. Each node of a record is assigned a log address.
