Abstract: The present disclosure describes methods, systems, and computer program products for optimizing single-value database read operations. One computer-implemented method includes initializing, by a computer, a single value cache associated with a created database table where a column of the database table contains a single or unique data value, verifying that the created database table is in a useable state, performing an operation on the database table, and retrieving the data value from the single value cache without locking the column containing the single or unique data value.

Abstract: Embodiments allow join operations to be performed upon encrypted database tables stored on an unsecure server (e.g., as part of a DBaaS offering), with reduced information leakage. Such secure join operations may be implemented through the combination of two cryptographic techniques: non-deterministic (randomized) searchable encryption; and attribute based encryption. The searchable encryption (e.g., Symmetric Searchable Encryption: SSE) allows join values to be revealed only for rows fulfilling additional predicate attributes that the client has filtered for, thereby offering fine granular security. The attribute based encryption (e.g., Key-Policy Attribute-Based Encryption: KP-ABE) avoids the unmanageable consumption of memory that would otherwise result from the creation of intermediate constructions on the server. Embodiments offer a solution reducing information leakage of join values not contained in the result of the actual database query.

Abstract: Technologies are described for facilitating replay of requests for database operations. A plurality of requests for database operations are received. Each of the plurality of requests includes a type, an access unit identifier, and a chronological identifier. Execution dependencies are determined between the plurality of requests based on the type, access unit identifier, and chronological identifier of each of the plurality of requests. The execution dependencies are stored.

Abstract: Secure substring searching on encrypted data may involve a first preprocessing comprising fragmenting a plaintext string slated for remote secure storage, in a plurality of overlapping plaintext substrings. A second preprocessing encrypts these substrings into ciphertexts (e.g., utilizing Frequency-Hiding Order Preserving Encryption) further including position information of the substring. A search index and a secret state result from the first and second preprocessing. The ciphertexts and search index are outsourced to a database within an unsecure server. An engine within the server determines candidate ciphertexts matching a query request received from a secure client. The engine returns ciphertexts to the client for decryption according to the secret state. Preprocessing may be delegated to a third party for outsourcing search index/ciphertexts to the server, and the secret state to the client.

Abstract: Parameter-based deployment control for database objects is provided, in which processes for deploying database artifacts into a database as database objects are implemented. Many different techniques may be used in executing such deployment processes, including whether and how to combine various deployment-related jobs, identify/record/assess/correct potential errors, govern or instruct artifact conversion operations, or generally manage available resources with respect to executing the deployment(s) efficiently. By providing for selectable parameter values that are executed in an efficient, e.g., hierarchical, manner, deployment procedures may be implemented in a highly efficient and customizable manner.

Abstract: In an example embodiment, an efficient paging algorithm is provided. A first request for hierarchical data is generated and sent to a backend located on a server device. A first flattened table containing hierarchical data responsive to the first request is received from the server device, the first flattened table containing a plurality of entries, each entry corresponding to a node in a sub-tree of hierarchical data responsive to the first request, and, for each of the plurality of entries, a magnitude value indicating a number of nodes underneath the node corresponding to the entry, in the sub-tree. One or more paging parameters are created based on one or more of the magnitude values. A second request for hierarchical data is generated based on the one or more paging parameters and sent to the backend. A second flattened table containing hierarchical data responsive to the second request is received.

The clustering application determines a first cluster of data items of a data set, the data items in the first cluster having first attribute values that are similar to each other within a first degree of similarity and determines a second cluster of data items of the data set, the data items in the second cluster having second attribute values that are similar to each other within a second degree of similarity. For visual analytics, the user interface receives a user selection of a third degree of similarity.

Abstract: Raw data is received that characterizes each of a plurality of transactions. The data can be received, for example, via an adapter coupled to at least one data source. At least one first table is populated using the raw data according to a normalized data model. At least one second table is then populated, by applying a key figure data model to transform and enrich the at least one first table, such that it is optimized for data analysis operations. The at least one second table can include a subset of data stored in the at least one first table and additional enrichment data. At least one data analysis operation can later be initiated on the data populated in at least one second table to characterize one or more aspects of the transactions. Data can be provided that characterizes the initiated at least one data operation.

Abstract: Disclosed herein are systems, methods, and computer program products for providing transaction-consistent snapshots of data stored in or associated with a database. An embodiment operates by receiving, at a source database, an update request to update data associated with a table stored at the source database, and modifying a value of a modification-in-progress data structure corresponding to the table to indicate that a modification is in progress for the table. The embodiment includes updating a value of a commit identification counter and a table time stamp associated with the table to indicate that cached data having a time stamp older than the updated time stamp are invalid. The embodiment further includes modifying the value of the modification-in-progress counter to indicate completion of table modification.

Abstract: Technologies are described for facilitating transaction processing within a database environment having a coordinator node, a first worker node, and at least a second worker node. The first worker node sends a request from to the coordinator node for at least a first synchronization token maintained by the coordinator node. The first worker node receives the at least a first synchronization token from the coordinator node. The first worker node assigns the at least a first synchronization token to a snapshot as a snapshot ID value. The snapshot is executed at the first worker node. The first worker node forwards the snapshot ID value to the at least a second worker node.

Abstract: Various embodiments of systems and methods to optimize compilation in distributed software projects via dynamic server cloning are described herein. The described techniques include receiving a compilation request comprising an update of a software product of a distributed software development project. Further, in one aspect, a server node clone is instantiated, e.g., from a resource pool, based on a server template. The server template corresponds to a latest successful compilation of the software product. In another aspect, the update of the software product is incrementally applied on the latest compilation at the server node clone. Once the update of the software product at the server node clone is confirmed as successful, the server template is updated to the build of the software product at the server node clone. The server node clone is subsequently released to the resource pool to free up the consumed resources.
