A method for cluster based searching for a value range stored in a storage system, the method may include receiving a request to find a certain value range within a set of information elements that are stored in a storage system; wherein the set of information elements comprises subsets of information elements associated with subset hash based filters; wherein different subsets of information elements are associated with different subset hash based filters; determining a certain cluster value of a certain cluster that comprises the certain value range; applying one or more hush functions on the certain cluster value to provide one or more hash results; and determining whether one or more members of the certain cluster are possibly in a subset of information elements, based on the one or more hash results and on a subset hash based filter of the subset of information elements; and when determining that the one or more members of the certain cluster are possibly in the subset then searching, within the subset, a matching information element that matches the certain value range.

A method for a first set of processors and a second set of processors comprises, the first set of processors processing a set of queries, as a result of a change in utilization of the first set of processors, processing the set of queries using the second set of processors. The change in processors is independent of a change in storage resources, the storage resources shared by the first set of processors and the second set of processors.

A virtual machine that includes a plurality of processes executes on a computer processor. A record-replay file, trace annotations, and an application program interface request are received into the computer processor. The trace annotations and application program interface request are translated into record-replay commands. The record-replay commands capture data from the record-replay file, and the captured data can be accessed via a programmatic interface.

A method of summarizing data files includes implementing, at a server, a storage event for a data file, analyzing the data file and creating a summary of the data file, and storing the summary linked to the data file.

Provided are a data archiving method and apparatus capable of providing a remote near-line data archiving function by receiving remote function invoking from a target system in which data is stored, providing the target system with a first function for archiving, in a storage system, at least some of the data stored in the target system over a network in response to the remote function invoking, and providing the target system with a second function for the query of the data archived in the storage system over the network.

One example technique includes receiving a request for accessing a file from a container process. In response to receiving the request, the technique includes querying a mapping table corresponding to the container process to locate an entry corresponding to a file identifier of the requested file. The entry also includes data identifying a file location on the storage device from which the requested file is accessible. The technique further includes retrieving a copy of the requested file according to the file location identified by the data in the located entry in the mapping table and providing the retrieved copy of the requested file to the container process, thereby allowing the container process to access the requested file.

Embodiments of systems and methods for the rules based distribution of managed content across heterogeneous storage distributed in a network environment are disclosed. In particular, certain embodiments may employ entity rules in association with a content management system. An entity rule may be a rule specifying a set of parameters and a destination secondary storage location. When the entity rule is evaluated by the content system, a set of content managed by the content management system responsive to the rule may be determined using the parameters of the rule. Responsive content can be determined, for example, by searching the content of the content management system based on the parameters. Responsive content may be moved from the primary storage location of the content management system to the secondary storage location specified by the entity rule.

Techniques for enabling user search of content stored in a file archive include providing a search interface comprising a search rules portion and an action rules portion, receiving a file archive search criterion comprising at least one search rule, and searching the file archive using the search criterion. The techniques also include generating a set of files filtered using the search criterion and performing an action specified in the action rules portion on a file included in the set of files.

A method and system for executing database queries in parallel using a shared metadata store. The metadata store may reside on a master node, where the master node is the root node in a tree. The master node may distribute query plans and query metadata to other nodes in the cluster. These additional nodes may request additional metadata from each other or the master nodes as necessary.

Aspects of the disclosure provide a data processing apparatus having interface circuitry and processing circuitry. The interface circuitry is configured to obtain data related to at least two resource accounts, and related to resource transfer of the at least two resource account. The processing circuitry configured to construct resource transfer relationships of the at least two resource accounts according to the data, calculate, based on the resource transfer relationships, similarity measurements between the at least two resource accounts according to a preset calculation rule, and output, according to the calculated similarity measurements, a resource account with a similarity measurement satisfying a preset condition.
