摘要： A computer-implemented method for natural batching of I/O operations on a replication log may include: 1) identifying a replication log that records the order of writes within a cluster replication system, 2) determining that the replication log is unavailable, 3) queuing incoming I/O operations for the replication log in a single batch while the replication log is unavailable, 4) determining that the replication log has become available, 5) ceasing queuing of incoming I/O operations for the replication log based on the determination that the replication log has become available, and 6) grouping a plurality of I/O operations in the single batch for processing in parallel by assigning a same generation number to the plurality of I/O operations. Various other methods, systems, and computer-readable media are also disclosed.

摘要： A host-based replication snapshot method. The method includes synchronizing a set of data objects stored at both a replication source node and a secondary node. The method further includes identifying changed data objects out of the set of data objects from the replication source node that have been modified during a time period between a first time and a subsequent second time. Metadata indicating the changed data objects from the replication source node is transmitted to the secondary node. A snapshot is then generated at the second time on the secondary node by using the metadata.

摘要： A method, in one embodiment, can include receiving a key and associated data via a computing device. Furthermore, the method can include searching a B+ tree data structure using the key to find a leaf node. The B+ tree data structure is stored by a persistent storage coupled to the computing device. The B+ tree data structure can include a first plurality of nodes that each contains a key-value entry that is not maintained in a sorted order based on its key. In addition, the key and associated data are appended to the leaf node. A sector that includes the leaf node and the key and associated data can be flushed to the persistent storage.

摘要： When a loss of connectivity between a first node in a cluster of nodes and a data store is detected, an input/output (I/O) request associated with an application that was executing on the first node is shipped to a second node in the cluster that is in communication with the data store. The application can be gracefully shut down on the first node, and the second node can execute the application and satisfy the I/O request.
