In various example embodiments, systems and methods for building data cubes to be stored in a cube store are presented. In some embodiments, a metadata engine generates the cube metadata. In further embodiments, cube data is generated by a cube build engine based on the cube metadata and source data. The cube build engine performs a multi-stage MapReduce job on the source data to produce a multi-dimensional cube lattice having multiple cuboids. In further embodiments, the cube data is provided to the cube store.

A light modulating liquid crystal cell, a display panel, and a display device are provided. The light modulating liquid crystal cell has a light-exiting area and a non-light-exiting area surrounding the light-exiting area and includes first pixels located in the light-exiting area. Each first pixel includes first sub-pixels, and each first sub-pixels includes a first transistor. The first sub-pixels include at least two first sub-pixels arranged in a first direction and at least two first sub-pixels arranged in a second direction, and the first direction intersects the second direction. In the first sub-pixels of one first pixel, gate electrodes of the first transistors are electrically connected to a same first scanning line, and source electrodes of the first transistors are electrically connected to a same first data line.

The example embodiments disclose a system and method, a computer program product, and a computer system for improving solid-state drive performance. The example embodiments may include generating, by an affinity adapter located external to the solid-state drive, a plurality of affinities for each of a plurality of data to a respective plurality of subdivisions of data of a solid-state drive, wherein each of the plurality of data is associated with a logical block address (LBA) and each of the respective plurality of subdivisions has a physical block address (PBA). The example embodiments may also include receiving a request to write first data having a first LBA to the solid-state drive, determining by the solid-state drive, at a first time, that the first data has an affinity with a particular subdivision of data of a solid-state drive based on the generated plurality of affinities, and writing the first data to a memory location of the solid-state drive, wherein the PBA of the memory location has the determined affinity.

Solid-state drive performance and lifespan based on data affinity

In an approach to intelligently choosing transport channels across protocols by drive type, one or more transport channels on a host are detected. One or more storage drive tiers on a target are detected. The one or more transport channels are mapped to the one or more storage drive tiers, based on performance. A transfer of a data between a host and the target is completed, using each transport channel and each storage drive tier.

Embodiments of the present disclosure relate to hotness based data storage for facilitating garbage collection. For target data to be stored into a flash drive, hotness of the target is determined, which indicates an expected update frequency of the target data. Then the in-use blocks in the flash drive are searched for a matching block for storing the target data, such that hotness of data being stored in the matching block matches the hotness of the target data. If no matching block is found, a free block is selected for storing the target data. The selection of the free block is based on the hotness of the target data and a degree of wear of the free block.

Hotness based data storage for facilitating garbage collection

A query language used to traverse a path in a graph-based model is provided. The system comprises a parsing module to parse a query comprising query phrases. The respective query phrases composed of an object-type identifier and a filter where the object-type identifier corresponds to respective repositories and the filter is used to identify at least a portion of the objects associated with the object-type in the respective repositories. A planning module identifies the respective repositories corresponding to the object-type identifier within each of the one or more query phrases and generates an execution plan describing data to be retrieved according to the respective repositories and results of a preceding query phrase within the query. A translation module translates the respective query phrases into respective translated queries that are readable by the respective repositories and including the filter. An execution module implements the execution plan using the translated queries.

Methods, systems, and computer program products for monitoring, aggregating, and correlating business events in real time and acting on the results with near zero latency, wherein each event is processed in the first order relative to the event density, are described herein. In an embodiment, the method operates by receiving historical values comprising keys and data fields at an analytic model. Rules associated with actions are applied to the historical values. Actions including updating data are executed pursuant to the rules, and then the method determines whether additional rules are to be applied; and performs actions associated with these additional rules until there are no remaining rules to apply. The method stores updated data in a database.
