Abstract: A client stores client metadata entries corresponding to a plurality of data objects. During a first phase of a synchronization process, the client sends one or more client metadata entries to a server. Each client metadata entry sent corresponds to a data object for which at least one metadata parameter has changed since a prior execution of the synchronization process. During a second phase of the synchronization process, the client receives from the server one or more server metadata entries, each having at least one parameter that has changed since a prior execution of the synchronization process. The client identifies any received server metadata entry that conflicts with a corresponding client metadata entry, requests a user to select from among a predefined set of conflict resolutions to resolve the conflict, and the performs an action in accordance with the conflict resolution selected by the user.

Abstract: An improved scalable object storage system includes methods and systems allowing multiple clusters to work together. In one embodiment, there is a multi-cluster synchronization system between two or more clusters. The multi-cluster synchronization system uses variable compression to optimize the transfer of information between the clusters. Compression is used not only to minimize the total number of bytes sent between the two clusters, but to dynamically vary the size of the objects sent across the wire to optimize for higher throughput after considering packet loss, TCP windows, and block sizes. This includes both the packaging of multiple small files together into one larger compressed file, saving on TCP and header overhead, but also the chunking of large files into multiple smaller files that are less likely to have difficulties due to intermittent network congestion or errors.

Abstract: To help a database administrator assess the impact of database server changes on applications, trace files are preprocessed into intermediate files with events sorted by generation order. Unused event classes and columns of a trace file are excluded, and pre-calculated data may be included. Intermediate files are then dispatched across a set of clients, and replay occurs in a synchronization mode or a stress mode. Synchronization mode releases events in submission order, whereas stress mode releases events in emulation of their original timing. Replay parameters include server idle time cap, query timeout value, a connect-time scaling factor for scaling time between trace start and connection login, and a think-time scaling factor for scaling the time between events on a replay client—database server connection. Each replay client generates a result file, which a replay controller aggregates for administrator analysis.

Abstract: A method for allowing client computers in a distributed object-based data storage system to interpret higher revision data structures. In one embodiment, clients request layout maps of objects to be accessed from respective storage managers in the system and then construct and execute directed acyclic graphs (DAG) to accomplish desired I/O operations for data access. When a client computer running an older software revision is not able to interpret a particular data organization supplied by the storage manager that was designed after that client's software was installed, the client sends to the storage manager a description of the desired data access operation. The storage manager, in turn, interprets a data layout scheme for a client on a per-access basis and returns to that client a DAG containing a data structure that describes the sequence of I/O operations necessary to effect the data access. The client can then execute the storage manager-supplied DAG to carry out the data access.

Abstract: A method and system for N-way synchronization of computer databases. Synchronization of computer databases is structured into three rounds, namely an agenda round, a query round and a report round.

Abstract: The claimed subject matter is directed to a file system watcher in the presence of different file systems to allow synchronization of replicated files distributed among different file systems without compromising the features of each file system. To synchronize the distributed replications, a platform independent synchronization manager creates a file system watcher for each file system associated with a replication of the file. The file system watcher monitors each object for events affecting the object or the object's constituent files, such as creation, deletion, change and rename. Notifications are sent to the synchronization manager, which consolidates the modifications and updates a locally stored replication, if necessary. The synchronization manager then sends a notification of an update to all other synchronization managers for all replications of the distributed file or folder.
