The namespace manifest can be updated after each put transaction is acknowledged, which minimizes the number of write operations required for a put transaction. Updates to the namespace manifest are batched, distributed, and processed concurrently and in parallel by the storage servers that store the corresponding shards. This reduces the latency that would otherwise exist in the object storage cluster as a result of a put transaction. Updates to namespace manifest shards optionally occur in a batch process using MapReduce techniques.

  • Patent number: 9612757
    Abstract: 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.

  • Patent number: 9542468
    Abstract: Data synchronization requires much time if synchronization is started from an initial state where synchronization between databases is not performed, and when a synchronized record is updated during the synchronization process, synchronization of records must be performed again, so that the amount of communication for synchronization is increased. Therefore, when starting synchronization, data synchronization is performed based on a method using a table indicating the synchronization statuses between databases, and at the final stage of synchronization, data synchronization is performed based on a query transmission method using update logs.
