The region divided preferential SQL rewrite operation makes it possible for a user to inference a machine SQL statement rewrite operation to optimize the SQL statement with more or less focus on different regions of the SQL. This operation combines the strength of using heuristic knowledge and understanding of data to rewrite the region of the SQL statement where the problem originates with the precision and efficiency of a machine SQL statement rewrite operation.

Abstract: Mechanisms are provided for maintaining variable size deduplication segments using fixed size extents. Variable size segments are identified and maintained in a datastore suitcase. Duplicate segments need not be maintained redundantly but can be managed by updating reference counts associated with the segments in the datastore suitcase. Segments are maintained using fixed size extents. A minor increase in storage overhead removes the need for inefficient recompaction when a segment is removed from the datastore suitcase. Fixed size extents can be reallocated for storage of new segments.

Abstract: Dynamic user training rules can be employed to organize content within a folder. Each folder can be associated with a dynamic rule that defines a number of attribute and weighting factor associations and a folder threshold. Each attribute and weighting factor association can identify an attribute that is common among the contents of the smart folder and associate a weighting factor with the common attribute. Whenever a user manually moves content into or out of the smart folder, the attribute and weighting factor associations and possibly the folder threshold can be updated accordingly, such as by adjusting a value of one or more weighting factors to better reflect how common they are after the content has been manually moved into or out of the folder. In this way, the dynamic rule is automatically updated in response to the user's interaction with the smart folder.

Abstract: Systems and techniques to deputize agents in a system to reduce a number of event logs received by a coordinator are described. An agent belonging to a group of agents may receive a request to select a deputized agent. The agent may determine data associated with a component hosting the agent and send the data to a selection agent. The agent may receive a message from the selection agent indicating that the agent is to be the deputized agent. The deputized agent may receive one or more event logs from other agents in the group, determine that at least one event log has a high priority, and send the at least one event log to the coordinator. The deputized agent may store the one or more event logs in a storage device accessible to the hardware component.

Abstract: A multidimensional synopsis of a stream of textual data pertaining to a particular subject can be generated. To produce the multidimensional synopsis, multiple dimensions that each includes concepts can be identified. The stream of textual data can then be analyzed to identify the occurrence of the concepts within elements of the stream. The multidimensional synopsis can then be produced by generating a score for each intersecting set of concepts from the multiple dimensions. Therefore, each score can generally represent a prevalence of the corresponding intersecting set of concepts within the stream of textual data.

Abstract: Techniques and mechanisms described herein facilitate the acceleration of data transfer protocols via client side de-duplication techniques for transmitting data from a client device to a networked storage system while maintaining protocol usage characteristics. while preserving the same presentation semantics to the users. A data chunk may be determined at a client device by parsing a data stream generated at the client device via a network storage protocol. A fingerprint for the data chunk may be identified by applying a hash function to the data chunk. A determination may be made as to whether the chunk is stored at a networked storage system by transmitting the fingerprint to the networked storage system via a network. The client device may transmit a block map update request message including information for updating a block map to the networked storage system.

Abstract: Systems and techniques for displaying timelines of event logs are described. A software application may identify event logs associated with an identifier, such as an IP address of a network element or a username. The software application may group the identified event logs based on specified criteria. The software application may determine multiple sessions in which an individual session includes a group of event logs arranged along a timeline. Sessions associated with a same network element may be displayed with a same magnitude. Sessions associated with different network elements may be displayed with different magnitudes. For example, a first timeline of event logs in a first session at a first network element may be displayed at a first height. A second timeline of event logs in a second session at a second network element may be displayed at a second height.
