Abstract: Systems and methods for storage pruning can enable users to delete, edit, or copy backed up data that matches a pattern. Storage pruning can enable fine-grain deletion or copying of these files from backups stored in secondary storage devices. Systems and methods can also enable editing of metadata associated with backups so that when the backups are restored or browsed, the logical edits to the metadata can then be performed physically on the data to create a custom restore or a custom view. A user may perform operations such as renaming, deleting, modifying flags, and modifying retention policies on backed up items. Although the underlying data in the backup may not change, the view of the backup data when the user browses the backup data can appear to include the user's changes. A restore of the data can cause those changes to be performed on the backup data.

Abstract: A Database Query Time Estimator (DQTE) module as a run-time tool to estimate and display the total time to complete a database query while the query is executing. The DQTE module invokes a runtime algorithm to compute the set of rows or blocks in a database that will be resulted at each step of a query's execution plan. The DQTE module may optimize the current execution plan to create one or more parent-child processes and may assign tasks to these processes to monitor the progress of each step in the execution plan. The progress of the child processes is then rolled up to the root parent level to come up with a time value, which is the Estimated Time of Arrival (ETA) to complete the whole execution of the query. The DQTE module may read only the header information of the database objects for a complete snapshot of the object.

Abstract: A method for processing queries includes a master device receiving a query from a client device, and interpreting the query to identify a data record identifier matching the query.

Abstract: Items within a data set can be redistributed to different partitions of a distributed data store according to modified hash values. A redistribution event may, in some embodiments, trigger the redistribution of a data set. Modified hash values for items in the data set may be generated according to a secondary hashing scheme to be used for identifying the location of a new partition to store the item instead of hash values based on current key values that identify a current partition that stores the item. Access can be provided to items based on the modified hash values to determine the new partition that stores the item after redistribution.

Abstract: A log file processing system sorts records from large log files and groups them by session without making a complete copy of the log files by capturing a subset of the log files in a sliding memory window and identifying all records in the window that form a complete user session. Records belonging to a complete session are output for analyzing, and the remaining records are output as raw log data for additional processing. Using a ring buffer to implement the sliding memory window, data structures are used to group records by session, to identify completed sessions, and to index into the ring buffer to retrieve records for completed sessions that are to be directly analyzed. Any records remaining in the ring buffer at the end of slide window processing may be output as raw log file data and are processed as incomplete or malformed session records. An embodiment of the log file processing system provides a significant improvement on the speed of data extraction from log files into analyzable session data.
