    Abstract: Embodiments of the present disclosure provide techniques for efficiently and accurately performing propagation of search-head specific configuration customizations across multiple individual configuration files of search heads of a cluster for a consistent user experience. The cluster of search heads may be synchronized such that the search heads operate to receive the configuration or knowledge object customizations from one or more clients from a central or lead search head. To reduce the amount of data that is transferred during propagation, the list of configuration or knowledge object customizations maintained in each search head is filtered from the list of the lead search head until a divergence point is determined. Once determined and communicated to the lead search head, the lead search head sends the configuration and knowledge object customization data that is absent from the internal list of the member search head.

  • Patent number: 11200207
    Abstract: Embodiments of the present disclosure relate to creating and maintaining a separate compliance store within a domain. Files that are committed within the domain are linked to the compliance store using canonical links. Canonical links are guaranteed to be non-erasable and non-rewritable for the duration of their retention period. When using a source cluster of nodes as a primary production cluster and a target cluster of nodes as a backup cluster, file data and canonical links can be synced from the source cluster to the target cluster to maintain compliance with data retention rules. Non-canonical links can be modified as necessary to ensure snapshot consistency when failover or failback occurs between a source cluster of nodes and a target cluster of nodes.

  • Patent number: 11188266
    Abstract: Techniques are provided for implementing write ordering for persistent memory. A set of actions are identified for commitment to persistent memory of a node for executing an operation upon the persistent memory. An episode is created to comprise a first subset of actions of the set of actions that can be committed to the persistent memory in any order with respect to one another such that a consistent state of the persistent memory can be reconstructed in the event of a crash of the node during execution of the operation. The first subset of actions within the episode are committed to the persistent memory and further execution of the operation is blocked until the episode completes.

  • Patent number: 11188422
    Abstract: The described embodiments set forth techniques for preserving clone relationships between files at a computing device. In particular, the techniques involve identifying clone relationships between files in conjunction with performing operations on the files where it can be beneficial to preserve the clone relationships. The operations can include, for example, preserving clone relationships between files that are being copied from a source storage device (that supports file cloning) to a destination storage device that supports file cloning. Additionally, the operations can include preserving clone relationships when backing up and restoring files between a source storage device (that supports file cloning) and a destination storage device that does not support file cloning. In this manner, the various benefits afforded by the clone relationships between files can be retained even as the files are propagated to destination storage devices that may or may not support file cloning.

  • Patent number: 11182405
    Abstract: Disclosed herein are system, method, and computer program product embodiments for providing a lock-free parallel log replay and synchronization scheme to support asynchronous table replication. By synchronizing a replica table with the server-side data and conducting subsequent updates using transaction logs via a replayer, locking of tables may be avoided. A consistent transactional state may be maintained by employing a replayer to mark the table as enabled instead of a synchronizer. The replayer may also deduce transitive closures among transactions and replay the transactions in parallel based on the deduced transitive closures to optimize playback. These techniques provide enhanced data availability and minimize database blocking and deadlocking while improving query performance.

  • Patent number: 11176115
    Abstract: Techniques are described for performing dependency locking to enable parallel execution of database server processes modifying the same object. In an embodiment, a DBMS receives a request to execute an operation on its managed database. The request may include an object identifier and a version identifier for a version of a database object, which is required for the successful execution of the operation on the database. The required version of the database object may not exist and may be generated only after the execution of another, second, operation on the database. The first database server process initiates execution of the earlier received operation on the database. The first database server process queries the first database for the version of the particular database object and determines that the version of the database object does not exist yet, in one embodiment.
