A method for establishing a connection between two nodes in a communication network without use of a centralized directory or mapping identifiers includes: receiving a lookup message from another node in the communication network that includes a lookup term; determining if a target node in a local directory cache can be identified that satisfies the lookup term; and, if such a node is identified, establishing a connection to the target node and forwarding the lookup message, or, if no such node is identified, forwarding the lookup message to other nodes in the network with which the node has an active communication connection.

Techniques for processing a data set include: partitioning the data set into portions each including rows of data of the data set, a different one of the portions is included in a different one of a pages of a table, and rendering the pages of the table. A first number of rows of the data set is determined for a first page. The first number of rows is determined in accordance with a first plurality of heights including a height of a header section, a height of a footer section, heights of a plurality of margins, a total height of each page of the table, and a height of each row of the table. A second number of rows is determined for a second page. The second number of rows is determined in accordance with a second plurality of heights including at least some of the first plurality of heights.

There is provided a system of generating a bitmap filter as part of a join operation. A query comprising a filter parameter is received and a first data source associated with the filter parameter is queried to identify an entry therein with an identifier corresponding to the filter parameter. Each entry of the first data source is identified by a corresponding identifier to differentiate the entries from one another. The system generates a bitmap filter corresponding to the filter parameter by identifying a single bit location in the bitmap filter that corresponds to an identifier of the entry corresponding to the filter parameter. Each identifier has a numerical value used to identify the bit location. A single bit location is assigned to the identifier and a bit is set at the assigned bit location such that there is one-to-one mapping between the identifier and the assigned bit location.

A system and method for managing tables in a storage system is described.

Computer-implemented methods and systems are disclosed for receiving and indexing a plurality of files for later querying, for dynamically generating scripts to be executed during a query of a data store, and for horizontally distributing a query and aggregating results of the distributed query.

A method is provided for retrieving a listing of keys associated with respective objects stored in an object storage system supporting a remote object access protocol. The keys include respective strings of characters encoded by means of a character encoding, and the method includes: obtaining a start key and an end key for defining a key interval for the listing; subdividing the key interval into key subintervals based on one or more intermediate keys; scanning the key subintervals, thereby retrieving a listing of the keys in the key subintervals; and the subdividing includes: representing the start key and end key as a start and an end numeric sequence according to the character encoding; and calculating the one or more intermediate keys as one or more intermediate numeric sequences from the start and end numeric sequences by means of arithmetic computation.

Disclosed are systems and methods for improving interactions with and between computers in content providing, generating, securing and/or hosting systems supported by or configured with personal computing devices, servers and/or platforms. The systems interact to identify and retrieve data within or across platforms, which can be used to improve the security and quality of data used in processing interactions between or among processors in such systems. The disclosed systems and methods provide added security features and functionality to media files through computerized, automated encoding and decoding of portions of media file content such that identified portions of the content are obfuscated upon display and communication to other users. The disclosed systems and methods provide a novel, computerized security feature(s) that protects data of media files from unintended exposure to third parties. The disclosed security features automatically prevent personal and/or private information from unwanted viewing and access from unauthenticated users.

A system for identifying complete account identifiers from partial account identifiers is provided. The system includes an account identification computing device including at least one processor and a memory device in communication with the at least one processor. The processor is configured to receive transaction data including unique merchant identifiers, build a merchant table using the transaction data, and receive a list including partial account identifiers. The processor is further configured to determine, for each unique merchant identifier, a number of candidate account identifiers and calculate at least one metric based on the number of candidate account identifiers. The processor is further configured to identify a source unique merchant identifier and match at least one candidate account identifier to a complete account identifier by matching one of the partial account identifiers to the at least one candidate account identifier.

An algorithmic TCAM based ternary lookup method is provided. The method stores entries for ternary lookup into several sub-tables. All entries in each sub-table have a sub-table key that includes the same common portion of the entry. No two sub-tables are associated with the same sub-table key. The method stores the keys in a sub-table keys table in TCAM. Each key has a different priority. The method stores the entries for each sub-table in random access memory. Each entry in a sub-table has a different priority. The method receives a search request to perform a ternary lookup for an input data item. A ternary lookup into the ternary sub-table key table stored in TCAM is performed to retrieve a sub-table index. The method performs a ternary lookup across the entries of the sub-table associated with the retrieved index to identify the highest priority matched entry for the input data item.

A backup manager for providing backup services includes persistent storage and a backup orchestrator. The persistent storage includes protection policies. The backup orchestrator generates a backup for a client based on the protection policies; obtains system metadata from the client; generates a backup map for the backup based on the system metadata; generates a backup hierarchy for the backup based on the backup map; and stores the backup and at least one selected from a group consisting of the backup hierarchy and the backup map.
