ASYNCRHONOUS CONSISTENT SNAPSHOTS IN PERSISTENT MEMORY STORES |
摘要 |
Crash recovery with asynchronous consistent snapshots in persistent memory stores of a processing environment. A processing environment includes a user program and infrastructure-maintained data structures. The infrastructure-maintained data structures include a log of updates made to program data structures and a snapshot of the state of the program data structures. The systems and methods include writing log entries in the log to a transient memory. The log entries correspond to store instructions and memory management instructions operating on a nonvolatile memory (NVM), and input/output (I/O) operations executed by program instructions of the user program. Each of the log entries represents an effect of a corresponding operation in the program instructions. The systems and methods also include creating a snapshot in the NVM after a consistent program point based on the log of updates. The snapshot provides a rollback position during restart following a crash. |
