  • Patent number: 10225341
    Abstract: A method, system and computer program product for implementing synchronization of state information in an efficient, scalable manner. A shared state server receives a request from a client device to access a scope containing state information. The scope is distributed over a partition(s) via the use of a “data grid” thereby increasing scalability. The shared state server relays the request to a data grid server responsible for maintaining the data grid comprised of an in-memory cache and partitions outside of the in-memory cache. The request includes a key associated with a value corresponding to the requested state information. The data grid server obtains the value associated with the key from its data grid and sends it to the shared state server to be relayed to the requesting client device. In this manner, the state information is stored in a scalable manner thereby improving the efficiency in synchronizing state information.

The neighbor data of the first plurality of data is added to a suspect queue. The priority to check the neighbor data is increased if the neighbor data is already in the suspect queue. Unsynced neighbor data is added to the unsynced queue. The priority for recovery of the data in the unsynced queue is determined. The priority is based on the vulnerability of the data. A data replica in the unsynced queue is recovered.

  • Patent number: 9614879
    Abstract: Method, software, and system for efficiently enabling n-way collaborative work using common software over a network of computers. In a preferred embodiment of the invention, each participant in a collaborative session starts up a common software application, which includes a collaboration component. This collaboration component is used to establish a common session that includes all interested parties. The collaboration component replicates operations performed on any one instance of said application to all other instances participating in the same session, so the effect is as if all members of the session were sharing a single instance of the application on a single computer. In one aspect, the collaboration component also supports broadcast of audio and video over a computer network, to enable session participants to see and/or hear each other, and further includes other features that support collaborative work.

  • Patent number: 9529881
    Abstract: Techniques are disclosed to determine differences between a source table and a target table in a database environment, as being persistent or transient. A first set of differences between the source table and the target table is determined at a first point in time. A second set of differences between the source table and the target table is determined at a second point in time subsequent to the first point in time. At least one of a set of persistent differences and a set of transient differences is determined. The set of persistent differences includes a set intersection of the first and second sets of differences, the set intersection being filtered based on matching non-key values of the differences. The set of transient differences includes a relative complement of the second set of differences in the first set of differences.

  • Patent number: 9460128
    Abstract: This disclosure relates to populating an aggregated sliding window view group comprising one or more internal views, and each of the internal views in group has its own interval. In some implementations of this disclosure, the aggregated sliding window view group can store the history of previous view results and each row in a view inside the aggregated sliding window view group can correspond to a fixed interval of time. In various implementations, a view inside the aggregated sliding window view group can be populated from lower-level sliding window views based on a relationship between the aggregated sliding window view and the lower-level sliding window views. In some implementations, a sliding window view can store a constant number of view results. The aggregated sliding window view group can provide a user with a convenient and efficient means for displaying multiple data aggregates associated with multiple periods of time simultaneously.

  • Patent number: 9424328
    Abstract: Techniques for assisting owners to remotely administer their digital content items stored at non-owners' personal computing devices. The techniques involve identifying owned content items from among content items stored in a synchronization replica that is synchronized with synchronization replicas at the non-owners' personal computing devices. The techniques further involve allowing owners to remotely perform certain administrative actions on owned content items. For example, in response to a command initiated at an owner's personal computing device, a network signal or signals can be sent to a synchronization agent installed on the non-owners' personal computing devices to automatically remove all owned content items from the synchronization replicas at the non-owners' personal computing devices.
