Abstract
Approaches for replicating data in a distributed transactional system. At a first node of a cluster, a per-transaction write set that comprises a plurality of write operations that are performed against a first data store maintained by the first node is committed. The per-transaction write set is replicated from the first node to a second node of the cluster. At the second node, the plurality of write operations, specified by the per-transaction write set, may be performed in parallel against a second data store maintained by the second node. At the second node, two or more threads may perform a portion of the plurality of write operations against data blocks stored within an in-memory buffer.
