Abstract:
Technologies for distributed durable data replication include a computing device having persistent memory that stores a memory state and an update log. The computing device isolates a host partition from a closure partition. The computing device may sequester one or more processor cores for use by the closure partition. The host partition writes transaction records to the update log prior to writing state changes to persistent memory. A replication service asynchronously transmits log records to a remote computing device, which establishes a replica update log in persistent memory. If the host partition fails, the closure partition transmits remaining log records from the update log to the remote computing device. The update log may be quickly replayed when recovering the computing device from failure. The remote computing device may also replay the replica update log to update a remote copy of the state data. Other embodiments are described and claimed.
