Abstract: Provided are systems and methods for managing asynchronous replication in a distributed database environment, wherein a cluster of nodes are assigned roles for processing database requests. In one embodiment, the system provides a node with a primary role to process write operations against its database, generate an operation log reflecting the processed operations, and permit asynchronous replication of the operations to at least one secondary node. In another embodiment, the primary node is the only node configured to accept write operations. Both primary and secondary nodes can process read operations. Although in some settings read requests can be restricted to secondary nodes or the primary node. In one embodiment, the systems and methods provide for automatic failover of the primary node role, can include a consensus election protocol for identifying the next primary node. Further, the systems and methods can be configured to automatically reintegrate a failed primary node.

Abstract: Presented is a system and method for evaluating relational database queries in a distributed system. An optimized query plan is received by a control node.

Abstract: A technique for protecting host data using, for example, snaps, asynchronous replication, and/or synchronous replication, includes storing both block-based objects and file-based objects in a common form—as files. With both block-based objects and file-based objects represented as the same type of underlying objects, data protection of both block-based and file-based objects is accomplished using a single set of data protection technologies, which are configured to perform data protection operations on files.

Abstract: An efficient and highly scalable method of sorting an input file in a processing system by using only a limited amount (i.e., a portion) of memory in the processing system, where that amount of memory is substantially smaller than the input file, is disclosed. The input file can be, for example, a fingerprint database for use in deduplication, and the processing system can be, for example, a network storage server. The merge phase is broken down into sub-phases, where each sub-phase takes a predetermined number of subsets of a fingerprint file to merge and writes them back as a sorted, merged group. The number of threads used to process these groups can depend on the number of central processing units (CPUs) present in the system and can be dynamically tuned to achieve desired level of performance.

Abstract: A cache server prefetches one or more web pages from an origin server prior to those web pages being requested by a user. The cache server determines which web pages to prefetch based on a graph associated with a prefetch module associated with the cache server. The graph represents all or a portion of the web pages at the origin server using one or more nodes and one or more links connecting the nodes. Each link has an associated transaction weight and user weight. The transaction weight represents the importance of the link and associated web page to the origin server and may be used to control the prefetching of web pages by the cache server. The user weight may be used to change a priority associated with a request for a web page. The user weight and transaction weight may change based on criteria associated with the origin server.
