Abstract: Techniques are provided for more efficient multi-row atomic, consistent, isolated and durable (ACID)-compliant transactions with snapshot isolation semantics (or just “multi-row transactions” for short). In some embodiments, the techniques are implemented in a computing system that includes a client application, a lightweight in-memory lease-based lock service, a multi-row transaction orchestrator, and an underlying database system. The transaction orchestrator implements a read protocol and a write protocol that provides support to the client application for carrying out multi-row transactions against the underlying database system irrespective of whether the database system itself supports multi-row transactions. The transaction orchestrator explicitly maintains transaction-level locks obtained from the lease-based lock service as part of the transaction protocol.

Abstract: A method is used in managing truncation of files of file systems. A request is received to delete a portion of a file of a file system. A set of extents associated with the portion of the file is determined where the file has been identified for deletion. A replica of the set of extents is created. The replica represents a state of the set of extents at a particular prior point in time. The portion of the file is deleted by updating metadata of the file. The replica is asynchronously deleted in background.

Abstract: A system for reconciling object for a configuration management databases employs statistical rules to reduce the amount of manual identification required by conventional reconciliation techniques. As users manually identify matches between source and target datasets, statistical rules are developed based on the criteria used for matching. Those statistical rules are then used for future matching. A threshold value is adjusted as the statistical rules are used, incrementing the threshold value when the rule successfully matches source and target objects. If the threshold value exceeds a predetermined acceptance value, the system may automatically accept a match made by a statistical rule. Otherwise, suggestions of possibly applicable rules may be presented to a user, who may use the suggested rules to match objects, causing adjustment of the threshold value associated with the suggested rules used.

Abstract: The present disclosure describes systems and methods for verification of data, including updates to applications, firmware, operating system libraries or other such data. This may be done through the use of a distributed ledger system to provide a secure anti-tamper mechanism for software and firmware updates that may be independently accessed and verified by any device. Distributed ledger systems, sometimes referred to as block chains, are online data storage systems with cryptography-based architecture providing links between records stored in “blocks”. Each block contains a hash of a previous block, providing a chain of linked blocks that are immutable: any alteration of a record changes the hash of the subsequent block, which changes the hash of the next subsequent block, etc. Accordingly, any modification of data is easily detectable.

Abstract: Examples relate to providing hardware assisted software versioning for clustered applications. In one example, virtualized global memory is accessible to application servers that provide a clustered application, where the clustered application includes multiple versions of a common data structure. After one of the application servers stores an element that is compatible with one version of the common data structure, other versions of the common data structure are located in the virtualized global memory. The element is then invalidated in the other versions of the common data structure to prevent access and translated directly in the virtualized global memory to the other versions of the common data structure. At this stage, the element can be validated in the other versions of the common data structure for access.

Abstract: The present solution relates to systems and methods for capturing and consolidating packet tracing in a cluster system. A multi-nodal cluster processing network traffic contains multiple nodes each handling some of the processing. A node may initially receive a flow and transfer processing of the flow to another node for processing. A flow may therefore pass from one node to another, from two nodes to many nodes. In some instances, it is helpful to generate a trace of a flow. For example, in debugging a network communication flow, a trace of the flow through the cluster can be helpful. Each node has a packet engine (“PE”) which processes data packets and can, when trace is enabled, generate a trace file for the packets processed at the respective node. A trace aggregator merges these distinct trace files into an aggregate trace for the cluster.
