Abstract
Methods, systems, and computer-readable media are described in which WAL records are replayed serially at the database sub-object level, thereby enabling parallelism for processes affecting a single database object without interfering with the consistency required to maintain ROS capability. WAL records are replayed serially at the B-Tree branch level, instead of existing approaches which serialize WAL record replay at the object or block level. Described examples may thereby enable multi-block operations (e.g., SPLIT) within the same B-Tree branch to be replayed in the correct sequence, thereby maintaining consistent reads during ROS. Multi-level dispatching at the object and sub-object levels may be used to minimize delays caused by operations affecting multiple branches of a database object.
