There is provided a method for searching a plurality of information sources using a multimedia element, the method may include receiving at least one multimedia element; generating, by a signature generator, for the at least one multimedia element at least one signature that is unidirectional, and yields compression; generating at least one textual search query using the at least one signature; wherein the generating of the textual search query comprises: (a) searching for at least one matching stored signature that matches one or more of the at least one signature; and (b) using a mapping between stored signatures and textual search queries, selecting at least one textual search query mapped to at least one matching stored signature; searching the plurality of information sources using the at least one textual search query; and causing a display of search results retrieved from the plurality of information sources.

In one implementation, a method includes identifying a first content-dependent feature associated with a data sector. The method further includes determining a baseline data sector associated with the data sector. The method further includes determining, by a processing device, a content-dependent delta between the first content-dependent feature and a second content-dependent feature of the baseline data sector. The method further includes providing the content-dependent delta and an indicator to the baseline data sector for storage on a plurality of storage devices.

Implementations described herein relate to methods, systems, and computer-readable media to obtain snapshots used for analysis of streaming data. In some implementations, a computer-implemented method includes receiving initial data that includes a plurality of identifiers and corresponding timestamps, generating and storing a snapshot based on the initial data, wherein the snapshot includes the identifiers and a corresponding status, receiving a data stream that includes a subset of the identifiers, activity information for each identifier in the subset, and corresponding timestamps. The method further includes periodically analyzing the data stream to obtain a delta that includes an updated status for each identifier in the subset, storing the delta separate from the snapshot. The method further includes receiving a request for identifiers that are active in a particular time period, and based on the particular time period, retrieving active identifiers from the data stream, the delta, or the snapshot.

A device (1) for processing transaction data (D1) including a plurality of records includes: a storage unit (2) that stores the transaction data; and a compressed data generation unit (5) configured to generate compressed data (D6) corresponding to the transaction data, based on a value of a transaction quantity included in the transaction data stored in the storage unit (2), wherein each of the records includes a value of at least one item, the item includes the transaction quantity, and the value of the transaction quantity includes a natural number other than 1.

Computer implemented methods for selective data deduplication in a multitenant environment are disclosed. Data deduplication of blocks written to a storage area associated with a tenant and redundant copies of the blocks written to other storage areas of other tenants is permitted or prevented based on tagging the first storage area associated with the tenant with a particular type of parameter. Responsive to detecting a write operation directed to the storage area tagged with a parameter indicating that deduplication is not permitted, a block to be written to the storage area is modified prior to hashing the block. Responsive to detecting a write operation directed to the storage area tagged with a parameter indicating that deduplication is permitted, a block to be written to the storage area is prevented from being modified prior to hashing the block.

A computer-implemented method for dynamic storage pricing in a multitenant environment is disclosed. The computer-implemented method includes dynamically modifying a storage cost for one or more tenants pointing to a block written to a storage area of the multitenant environment based, at least in part, on detecting a change in a number of tenants pointing to the block.

Mechanisms are provided for adjusting a configuration of data stored in a storage system. According to various embodiments, a storage module may be configured to store a configuration of data. A processor may be configured to identify an estimated performance level for the storage system based on a configuration of data stored on the storage system. The processor may also be configured to transmit an instruction to adjust the configuration of data on the storage system to meet the service level objective when the estimated performance level fails to meet a service level objective for the storage system.

A data deduplication method includes receiving an overwrite request sent by an external device, where the overwrite request carries a data block and a first address into which the data block is to be stored, determining whether an overwrite quantity of the first address exceeds a first threshold within a time period [t1, t2], where both t1 and t2 are time points, and t2 is later than t1, and when the overwrite quantity of the first address exceeds the first threshold within the time period [t1, t2], skipping performing a deduplication operation on the data block or when the overwrite quantity of the first address does not exceed the first threshold within the time period [t1, t2], performing a deduplication operation on the data block.

Embodiments of the invention make consumer application adoption more efficient by giving suppliers access to the desired target audience by displaying the applications to the right audience. Suppliers can provide criteria for the kinds of users they are looking to target using constraints. Embodiments of the invention enable viewers that match the constraints to see the service. The user gets to see an automatically generated application set, that is instantly available, with a high probability of containing the application the user is likely to seek. Identity and Payment support are built into the platform, such that the user no longer needs to register with each application or set up payment with each application. In addition, the platform reduces bandwidth consumption, storage front print, and power consumption of the user device by choosing when and which modules to download to the user device.

A memory tier including persistent memory (PMEM) devices is established in nodes of a cluster system having a deduplicated file system. At least a portion of metadata generated by the deduplicated file system is persisted to the memory tier. The portion of metadata includes an index of fingerprints corresponding to data segments stored by the deduplicated file system to a storage pool. A determination is made that an instance of the deduplicated file system has failed. A new instance of the deduplicated file system is started to recover file system services by loading the index of fingerprints from the memory tier.
