A computer implemented system and method allow database performance testing and improvement. The method comprises using a database system (DBS) for embedding a virtual resource simulation system (VRSS) into a node of the DBS, loading a new configuration parameter of a database into the VRSS, receiving, by the VRSS from the DBS, an action control block (ACB), and dynamically activating and assigning a service task by a service task dispatcher of the VRSS to process the ACB. The method further comprises simulating a process of database execution based on a content of the ACB by creating a limited database internal data structure that is based on the ACB and the new configuration parameter, and manipulating the limited database internal structure to produce a simulation result. The method further comprises utilizing a metric associated with the simulation result of the new configuration parameter in the simulated process of database execution. |

Automatic tuning of thresholds and weights for pair analysis in a master data management system
An approach for tuning a data management system is provided. A processor retrieves one or more samples pairs of record data. A processor determines an error rate regarding the performance of a matching operation of a data management system based on the one or more sample pairs. In response to the error rate being above a value, a processor adjusts at least one threshold value associated with the matching operation of the data management system. |

Persisting distributed data sets into eventually consistent storage systems
Embodiments of the present systems and methods may provide the capability ensure that data is persisted and accessed correctly without depending on eventually consistent list operations on the object store. For example, in an embodiment, a computer-implemented method for data distribution may comprise attempting to persist a plurality of data parts from a plurality of processing tasks, generating a manifest including information indicating those attempts to persist data parts that have succeeded, and persisting the manifest with the data parts that have been successfully persisted. |

“Bouncing” IO pattern for replication protocols
Systems and methods for a bouncing replication protocol are described herein. The system can include a replication cluster including a plurality of servers and a master controller that can receive a first request to replicate a first transaction and execute a batching process to replicate the first transaction. The batching process can include selecting a first server for replication of the first transaction, determining that a pending acknowledgement from the selected first server has not been identified, adding the first transaction to a first batch for the first server, and sending the first batch including only the first transaction. The master controller can receive a second request to replicate a second transaction, execute the batching process with the master controller to replicate the second transaction, which executing of the batching process includes adding the second transaction to a second batch including a plurality of transactions, receive an acknowledgement indicative of completion of replication, and send the second batch upon receipt of the acknowledgement indicative of completion of replication. |

System and method for information slingshot over a network tapestry and granularity of a tick
Systems and methods for file transfer and processing in a network environment are disclosed. In one embodiment, the system may comprise one or more processors. The one or more processors may be coupled to a first device. The one or more processors may be configured to retrieve a file from a file queue. The file may be stored in a local store of the first device. The file may be transferred from a second remote device via Remote Direct Memory Access. The one or more processors may further be configured to determine if the file is complete. The one or more processors may further be configured to remove the file from the file queue, if the file is determined to be complete. |

Cloned virtual machine disk replication
One or more techniques and/or computing devices are provided for replicating virtual machine disk clones. For example, a first storage controller, hosting first storage, may have a synchronous replication relationship with a second storage controller hosting second storage. A virtual machine, within the first storage, may be specified as having synchronous replication protection. Accordingly, virtual machine disk clones of a virtual machine disk of the virtual machine may be replicated from the first storage to the second storage. For example, virtual machine disk clones may be synchronous replicated, replicated by a resync process invoked by a hypervisor agent, and/or stored and replicated from a clone backup directory. |
