Abstract: A primary write request that is to modify a primary portion of primary data stored in a primary storage node is received. The primary write request is to be replicated to create a current secondary write request. The current secondary write request is to modify a current secondary portion of secondary data that is stored in a secondary storage node. A current data range of the current secondary portion is determined. A determination is made of whether a previous secondary write request is in process of modifying a previous data range that at least partially overlaps with a current data range of the current secondary portion. Execution of the primary write request is suspended, until the previous secondary write request has completed updating the secondary storage node.

Abstract: A system that implements a data storage service may store data on behalf of storage service clients. The system may maintain data in multiple replicas that are stored on respective computing nodes in the system. Updates to the stored data and to the membership of replica groups are propagated as replicated log records. A replica receiving a log record may compare metadata in the received log record to corresponding metadata in a log record that was previously appended to its log to determine a response. The metadata may include a sequence number, a lock generation identifier, an epoch identifier, or an indication of an epoch change. The replica may append the received log record to its log, drop the received log record, or cache the received log record for future use. If a log conflict indicates an invalid log stream branch, one or more log records may be deleted.

Abstract: Various embodiments describe multi-site cluster-based data intake and query systems, including cloud-based data intake and query systems. Using a hybrid search system that includes cloud-based data intake and query systems working in concert with so-called “on-premises” data intake and query systems can promote the scalability of search functionality. In addition, the hybrid search system can enable data isolation in a manner in which sensitive data is maintained “on premises” and information or data that is not sensitive can be moved to the cloud-based system. Further, the cloud-based system can enable efficient leveraging of data that may already exist in the cloud.

Abstract: A computer-implemented method for providing security to access and store data may include transferring first information for display from a token device having a memory to a first computing device at a first time, the token device connected to the first computing device and the first information describing public data stored on the token device.

In response to receiving the request to retrieve a root directory of private data, the root directory may be requested by establishing a wireless connection between the token device and a server computing device, transferring the root directory name to the server computing device, wherein the root directory name is used as a password to retrieve the root directory, and receiving the root directory from the server computing device by the token device.

Abstract: Paxos transactions are pipelined in a distributed database formed by a plurality of replica servers. A leader server is selected by consensus of the replicas, and receives a lock on leadership for an epoch. The leader gets Paxos log numbers for the current epoch, which are greater than the numbers allocated in previous epochs. The leader receives database write requests, and assigns a Paxos number to each request. The leader constructs a proposed transaction for each request, which includes the assigned Paxos number and incorporates the request. The leader transmits the proposed transactions to the replicas. Two or more write requests that access distinct objects in the database can proceed simultaneously. The leader commits a proposed transaction to the database after receiving a plurality of confirmations for the proposed transaction from the replicas. After all the Paxos numbers have been assigned, inter-epoch tasks are performed before beginning a subsequent epoch.

Abstract: A data operation method and device, relate to the storage field is presented. The data operation method and device can implement, during modification of a data strip in a storage device, data sending and receiving performed only for a storage device that requires modification. Other irrelevant storage devices do not consume a disk throughput and traffic, thereby reducing a disk throughput and usage of a network resource, that is, reducing a write penalty. A client sends both new and old version numbers to a storage device corresponding to a data strip that does not need to be modified, so that the corresponding storage device compares a version number of the data strip stored by the storage device with the old version number sent by the client. When the two version numbers are consistent, the version number in the storage device is updated to the received new version number.

Abstract: Techniques for restoring point-in-time and transaction consistency across consistency groups between a first and a second independent database management system (DBMS) for a disaster recovery. Several consistency groups (CGs) are defined for replication. For each CG in the first DBMS data changes are transmitted to a second DBMS. A timestamp representing a most recently received commit log record or a heartbeat during periods of inactivity for a CG is stored in a database table at regular intervals. At regular intervals, the timestamp is compared with timestamps for other CGs to identify a common time at which data to be applied to the CGs in the second DBMS have been received into a recoverable data store. The received data is applied to the CGs in the second DBMS up to the common time.

Abstract: Each of a plurality of Worker processes are allowed to perform any and all of the following tasks involving logged work items: (1) reading a subset of the work items from a log; (2) sequentially ordering work items for corresponding data objects; (3) applying a sequentially ordered set of work items to a corresponding data object; and (4) transmitting a subset of work items to a Worker process running on another database server in a cluster, if necessary. These tasks can be performed concurrently, at will, and as available, by the Worker processes. An improved checkpointing technique eliminates the need for the Worker processes to get to a synchronization point and stop. Instead, a Coordinator process examines the current state of progress of the Worker processes and computes a past point in the sequence of work items at which all work items before that point have been completely processed, and records this point as the checkpoint.
