Abstract: A system can apply file placement rules to dynamically place files and directories within file system views backed by objects in an object storage system. After detection of an update to a first file system view that causes an update of an object in a storage grid, an object manager begins evaluation of file placement rules against metadata of the object. For each file placement rule that is triggered, the object manager determines identifies gateways that export the first file system view. The object manager then instructs the gateways to update their representations of the first file system view. The disclosed embodiments may be able to scale to managing hundreds of billions of files spanning thousands of file system views, especially in the presence of disconnected operation.

Abstract: A method for updating and formatting a local file is described. An update file, having a newer version of the local file, is accessed from a server over a network and a list of new hash values corresponding to data blocks of the update file is retrieved. Divisions between the data blocks are located when a value of a rolling checksum reaches a particular value, the data blocks being of variable size. New hash values of the update file are compared with local hash values of the local file. For each of the new hash values not having a matching local hash value, the corresponding data block is downloaded from the server and written to a new file. For each of the new hash values having a matching local hash value, the corresponding block is copied from the local file to the new file.

Abstract: Information from source databases is retrieved and stored on a database storage system. Multiple point-in-time copies are obtained for each database. A source database may contain partitions comprising sets of database tables. A partition is imported into a virtual database created. The database storage system validates the partition before importing, by checking whether the partition includes database tables that refer to database tables outside the partition. A partition imported in a virtual database may be rewinded to an older state or refreshed to a more recent state. Multiple partitions may be included in a virtual database and the state of each partition modified independent of the state of the remaining virtual database including the other partitions. Multiple versions of the same partition corresponding to different points in time are incorporated in the same virtual database, thereby allowing a query to process different versions of the same database table.

Abstract: An interactive tag cloud provides an intuitive interface to large data volumes. Where the data is a large table, an overview afforded by the tag cloud may contain relevant table information ranked by priority and volume, represented in different categories. The tag cloud may be used to filter that big data in an efficient manner. This allows an ordinary (i.e., non-developer) user of the database to quickly assess high level contours of the data volumes, and also to filter that data in order to focus on specific tasks. The interactive tag cloud visualization may indicate data priority according to frequency of incidence of a dimension in database records, or according to other criteria such as importance derived from date information. The tag cloud affords visibility to aggregated big data content and also of filtered data, prior to the user having to immediately drill down in order to access details thereof.
