Abstract: A savepoint is initiated in an in-memory database system that is associated with a plurality of modified pages and comprises a pre-critical phase, a critical phase, and a post-critical phase. Thereafter, as part of the critical phase, a physical page number is assigned to each page in the critical phase. Further, as part of the critical phase, each page assigned a physical page number is individually locked. Subsequently, each page is handed over from a corresponding first thread to a corresponding second thread to copy such page into a corresponding shadow page as part of the post-critical phase.

Abstract: Some embodiments provide a non-transitory machine-readable medium that stores a program. In response to receiving a first query for a set of data, the program generates a first query execution plan based on the first query. The program further executes the first query execution plan in order to generate a first result set comprising the set of data. The program also stores the first query execution plan in a cache. The program further replaces the first query execution plan in the cache with a second query execution plan. The second query execution plan includes a query hint applied to the first query execution plan. In response to receiving a second query for the set of data, the program also retrieves the second query execution plan from the cache. The program further executes the second query execution plan in order to generate a second result set comprising the set of data.

Abstract: Some embodiments provide a program that receives, from a first system, a copy of master data. The program also receives a master data modification rule. The program further receives, from a second system, a first request to modify a value of a second field of data in the second system with a new value. In response to the first request, the program also identifies the master data modification rule. The program further performs a set of validation operations specified in the master data modification rule. Based on the performance of the set of validation operation, the program also modifies the first field in the copy of the master data with the new value based on the supplier identifier and sends a second request to the first system to modify the first field in the master data managed by the first system.

Abstract: A flexible approach for storing time series data, utilizes multiple representations in order to achieve optimization amongst various dimensions such as covered time period, accuracy, compression model, and storage medium. A first aspect selectively provides different representations for various portions of a time series along the time axis (horizontal). In this horizontal aspect, a first compression model may be applied to store data occurring during one period in a time series, while a different compression model is applied to store data during another period. In a separate (vertical) aspect, time series data over a same time period may be saved in multiple representations using different compression models. While increasing demands on memory, such vertical storage can afford efficient access for specific purposes (i.e., analytical).

The compiled core application software is transmitted to a second server associated with the cloud storage. An application based on the compiled core application software and the compiled dependency software may be executed.

Abstract: Dictionary encoding in a table of a database system is initiated using a single page chain. The database system includes a plurality of processor cores and each page chain includes a plurality of chained pages. Thereafter, n additional page chains are generated for use by the dictionary encoding when the count of pages used by the dictionary encoding reaches a pre-determined limit. Generation of additional page chains is later ceased once the number of additional page chains n is equivalent to a number of available processor cores. Related apparatus, systems, techniques and articles are also described.

Abstract: The present disclosure generally relates to a software application runtime having dynamic evaluation functions and parameters. A dynamic evaluation engine of an application's runtime accepts evaluation requests from methods of a software application. A request can be associated with an identifier for a method of the software application. The method identifier can be associated with one or more dynamic evaluation functions having one or more dynamic evaluation parameters. When the dynamic evaluation engine receives a request from an application method, the dynamic evaluation engine can determine the one or more current dynamic evaluation functions or parameters to use with the request. The dynamic evaluation engine can return an evaluation result to the method. The dynamic evaluation engine can be in communication with a repository, such as a central repository, providing a unique mechanism to look up dynamic evaluation functions and parameters, which can be imported into the application's runtime.

Abstract: Described herein is a framework to facilitate vehicle position planning. In accordance with one aspect of the framework, transition information is determined based on the vehicle data, wherein the transition information includes pairs of starting and ending road segments and corresponding passenger states. Short-term demand for vehicles may be calculated based on the transition information and the historical transactional records. The short-term demand may then be used to generate a cruising recommendation.

Abstract: A method may include executing a calculation scenario at a database. The calculation scenario may include a parent multiprovider aggregating data from a child multiprovider. The calculation scenario may be executed by mapping a first count keyfigure of the child multiprovider to a first sum keyfigure of the parent multiprovider if the child multiprovider aggregates data from part providers but not from multiproviders. A second sum keyfigure of the child multiprovider may be mapped to the first sum keyfigure of the parent multiprovider if the child multiprovider aggregates data from multiproviders but not from any part providers. The first count keyfigure of the child multiprovider may be mapped to a second count keyfigure of the parent multiprovider and the second sum keyfigure of the child multiprovider may be mapped to the first sum keyfigure of the parent multiprovider if the child multiprovider aggregates data from part providers and multiproviders.

Abstract: A dynamic data service accepts requests for database operations from a client application, where the requests can be associated with a property, including a particular data member, of a data model template. The property has at least one attribute that can be instantiated in a plurality of configuration values. The property is instantiated with the at least one attribute having a configuration value that is appropriate for fulfilling a client request, including being instantiated a plurality of times with a plurality of configuration values. The dynamic data service can send the request to a database for execution and return execution results to the client application. The dynamic data service can allow for the more flexible design of client applications, as the client applications can use different configuration values, or can use combinations of configuration values.

Abstract: In an example embodiment, one or more changes to one or more objects in the software object database are received from a developer. A change list is generated based on the one or more changes. An object definition is exported for every object in the change list from a first schema in the database to a second schema in the software object database. A first object in the second schema is activated by mapping a logical schema name specified in the object definition for the first object to a corresponding physical schema name and creating or altering the first object in the second schema using the physical schema name.
