  • Patent number: 11048722
    Abstract: In one aspect, performance optimization for data persistency in asynchronous replication setups includes creating at a source site of a data replication system, a snapshot (snapshot N) of input/output (IO) requests as part of a replication cycle, computing a delta of snapshot N and a previously created snapshot (snapshot N?1), and transmitting the delta to a target site of the data replication storage system. An aspect further includes storing, at the target site, snapshot N?1 during transmission of the delta, and caching the delta to a non-persistent storage device. Upon determining an occurrence of a loss event at the target site, a further aspect includes transmitting, by the target site, a request to retransmit the delta, retransmitting, by the source site, the delta to the target site, caching the delta to the non-persistent storage device until successful transmission of the delta, and committing the transmitted delta to permanent storage.

  • Patent number: 10769036
    Abstract: Embodiments of the disclosure provide techniques for updating a distributed transaction log on a previously offline resource object component using distributed transaction logs from active host computer nodes from separate RAID mirror configurations. Each component object maintains a journal (log) where distributed transactions are recorded. If a component object goes offline and subsequently returns (e.g., if the node hosting the component object reboots), the component object is marked as stale. To return the component object to an active state, a distributed resources module retrieves the journals from other resource component objects from other RAID configurations where the data is mirrored. The module filters corresponding data that is missing in the journal of the previously offline corresponding object and merges the filtered data to the journal.

  • Patent number: 10296498
    Abstract: According to embodiments, reconfiguration of lock masters for a cluster of nodes is optimized using coordinated hash indexes to index into the master hash table and into local hash tables stored on the nodes of the cluster. A DBMS uses a hybrid hash index, a portion of which represents a corresponding master hash index, to index into both the master hash table and into a local hash table for a given lock. The hash index used to store lock metadata in a particular local hash table bucket, on a particular node, encodes the lock master index, for a master hash table, to which the locks in the local hash table bucket correspond. Only the portions of the local hash table on the lock master that correspond to the index of the master hash table bucket need to be scanned in order to perform needed tasks for lock master reconfiguration.

  • Patent number: 9807190
    Abstract: Described herein are systems, devices, and methods for content delivery on the Internet. In certain non-limiting embodiments, a caching model is provided that can support caching for indefinite time periods, potentially with infinite or relatively long time-to-live values, yet provide prompt updates when the underlying origin content changes. In one approach, an origin server can annotate its responses to content requests with tokens, e.g., placing them in an appended HTTP header or otherwise. The tokens can drive the process of caching, and can be used as handles for later invalidating the responses within caching proxy servers delivering the content. Tokens may be used to represent a variety of kinds of dependencies expressed in the response, including without limitation data, data ranges, or logic that was a basis for the construction of the response.

  • Patent number: 9710438
    Abstract: Architecture that facilitates offline/online interaction with online collaboration documents or pages such as for wikis and/or notebooks. More specifically, for every proto link employed in a page, a unique object ID is provided. The client, whether online or offline, uses the object ID as the page's object ID when a target page is created at the time of resolving the associated proto link (e.g., when a user clicks on a proto link to navigate to the proto page). When an offline client connects to an online state, changes are synchronized (synced). All the pages created offline from the same proto link will have the same object ID and the content of the pages are then synced correctly under the same page ID and name.

  • Patent number: 9678879
    Abstract: Methods for encoding file system metadata are described herein. According to one embodiment, a file system cache is maintained including information representing relationships between inodes and disk blocks of a disk having disk sections. Each disk section includes a data segment and a header encoding metadata for describing the data section of each disk section. The metadata is encoded using a set partitioning algorithm and each set represents a set of disk blocks. In response to a file system request for reading a disk section, metadata associated with the disk section is retrieved and decoded to extract information representing a relationship between inodes and disk blocks associated with the requested disk section. The file system request is then serviced using the decoded metadata and the associated data segment and one or more entries of the file system cache are updated using the decoded metadata.

  • Patent number: 9665400
    Abstract: A method and system for distributing tasks from an external application among concurrent database application server instances in a database system for optimum load balancing, based on consensus among the instances. Each application instance identifies a task partition ownership by those in a membership group based on a time window and generates a new membership group and partition ownership based on the current partition ownership. The instance makes the new membership group and partition ownership known to other members by recoding them in the membership table and partition map. Each participation by an instance in the membership group is identified by a random number. The new membership group and partition ownership are generated and adjusted based on an average partition allocation to achieve consensus among the instances.

  • Patent number: 9578130
    Abstract: Methods and apparatus for distributed locking interfaces are disclosed. A state manager implements programmatic interfaces for distributed locking operations. In response to a queue-for-lock request for a registry element received via an interface, the state manager provides to the requester, a reference to a first asynchronous computation. The first asynchronous computation comprises an insertion of a lock request into a queue of waiters for a lock on the element. In response to a request for a result of the computation, the state manager transmits, after the lock request has been inserted into the queue of waiters, a notification of the insertion of the request. The notification in turn includes a reference to a second asynchronous computation. The second asynchronous computation comprises a grant of the lock on the particular element to the requester.
