Abstract: In an approach for automatic vertical partitioning of fact tables in a distributed query engine a processor analyzes a sample end-user workload of queries to extract filter predicates associated with each of multiple fact tables relating to a big data store. A processor, for each fact table, and for each column in the fact table to which a filter predicate is applied and where coarsification is required, generates a candidate partitioning expression incorporating an adjustment to a coarsification function based on a data distribution of values in the column. A processor scores the candidate partitioning expressions for each fact table based on cost data relating to the sample end-user workload and selects one or more candidate partitioning expressions to optimize partitioning of each fact table with each partition data being placed in a separate directory in a distributed file system.

Abstract: Certain tasks related to processing layer 7 (L7) data streams, such as HTTP data streams, can be performed by an L7 assist circuit instead of by general-purpose CPUs. The L7 assist circuit can normalize URLs, Huffman decode, Huffman encode, and generate hashes of normalized URLs. A L7 data stream, which is reassembled from received network packets, includes an L7 header. L7 assist produces an augmented L7 header that is added to the L7 data stream. The CPUs can use the augmented L7 header, thereby speeding up processing. On the outbound path, L7 assist can remove the augmented L7 header and perform Huffman encoding such that the CPUs can perform other tasks.

Abstract: A modulator for a flying-capacitor type multilevel converter receives, at an input, a time-variant reference signal and provides, at an output, a sequence of target levels, to provide switching signals for switching between discrete output levels of the multilevel converter according to the shape of the reference signal. The modulator determines a critical level as an intermediate output level of the multilevel converter which is closest to the level of the reference signal; and outputs only target levels corresponding to output levels different from the critical level.

Abstract: Examples described herein include systems and methods for management of contextual notifications on user devices. Entities can be categorized as VIP status based on scoring profiles sent from a management server to the user device. Applications on the user device can implement an SDK that reads the profiles and sets certain actions to boost scores and others to reduce scores. These local VIP scores can be sent periodically from the user device to the management server. The management server can use them in conjunction with global VIP scores for the same entities to create aggregated VIP information. This can be sent back to the user device, allowing the user device to then visualize different notifications or workflows based on whether an entity's aggregated VIP information exceeds one or more thresholds.
