Dynamic control of scan signals in AMOLED displays
This document describes systems and techniques for dynamic control of scan signals in active-matrix organic light-emitting diode (AMOLED) displays. Displays in portable electronic devices, such as smartphones, include tens of thousands of pixels. Scan signals in the display control the brightness and color of individual pixels. A leading source of power consumption in AMOLED displays, however, is the parasitic capacitance in the scan lines that carry the scan signals. As the frame rate of AMOLED displays has increased, the frequency of scan signals and the associated parasitic capacitance has also increased. The described AMOLED display can dynamically control the number of pulses in scan signals to reduce power consumption without degrading image quality. |

Systems and methods for real-time analytics detection for a transaction utilizing synchronously updated statistical aggregation data
A system and method for performing real-time analytics detection where a current profile update is derived from a current incoming transaction for an entity and stored in a profile update table, an up-to-date profile for the entity is derived from the most recent profile stored in a profile table and from all recent profile updates stored in the profile update table for the entity which are more recent than the last time the most recent profile was last updated, the up-to-date profile is utilized to perform the detection, and, the current profile is updated in a consistent manner, without utilizing an update lock on the profile table, by only updating the profile in the profile table based on the recent profile updates which are earlier than a current time minus a synchronization period which is larger than a maximum potential time difference between different clocks in the system. |

Data storage using vectors of vectors
The systems and methods described here can reduce the storage space required (memory and/or disk) to store certain types of data, provide efficient (fast) creation, modification and retrieval of such data, and support such data within the framework of a multi-version database. In some embodiments, the systems and methods can store each field of a set of records as a vector of values, e.g., a data vector. A set of records can be represented using a vector hash vector, or “vhash” vector, wherein each element of the vhash vector contains a unique identifier of a data vector, based on a cryptographic hash of the data vector. A header table can store associations between labels and “vhash” vectors that pertain to those labels. Identical data vectors can be re-used between different record sets or vhash vectors needing that vector, thus saving space. |

Deduplicating full and partial block matches
A technique for performing deduplication traverses a deduplication database and assigns digest values in the database to buckets, where each bucket covers a respective range of digest values. To deduplicate a particular candidate block, the technique generates a digest from the candidate block and searches for the computed digest in a subset of the buckets, where the subset is selected based on the computed digest. If a target block providing an exact match or a suitably close partial match is found in the subset of buckets, the technique effects storage of the candidate block at least in part by providing a reference to the target block. |

Detecting data mapping relationship within database system and optimizing data operation
Embodiments of the present invention provide systems and methods for detecting data redundancy within a database and optimizing data access operations. The embodiments identify a candidate column to determine the relationship between the candidate column against the remaining columns. The system calculates the vector angles of rows based on candidate column pairs and determines the difference in the angle between the candidate column and the corresponding rows of data in the comparison columns. If the candidate column has a greater angle than the compared column, then the compared column is identified as redundant and is marked for the decluttering process. |

Efficient clustered persistence
The systems and methods disclosed herein relate to using the clusters of a file to store versioning of a dataset. When the dataset is initially stored, a file is created that is twice the size of the dataset. The file may include one cluster (or a first set of clusters) that is marked as active and a second cluster (or a second set of clusters) that are marked inactive. The dataset is initially saved to the active cluster(s), and a version number is stored with the dataset. When the dataset is next saved, an application scans the file to determine whether there is (or are) an inactive cluster(s). If there is an inactive cluster(s) the second version of the dataset is saved to the inactive clusters. Both clusters are then marked active. |

Share replication between remote deployments
Provided herein are systems and methods for an efficient method of replicating share objects to remote deployments. For example, the method may comprise modifying a share object of a first account of a data exchange into a global object wherein the share object includes grant metadata indicating share grants to a set of objects of a database. The method may further comprise creating, in a second account of the data exchange, a local replica of the share object on the remote deployment based on the global object, wherein the second account is located in a remote deployment. The set of objects of the database may be replicated to a local database replica on the remote deployment and the share grants may be replicated to the local replica of the share object. |

Region-integrated data deduplication implementing a multi-lifetime duplicate finder
In one embodiment, a deduplicating storage system includes a processor and logic integrated with and/or executable by the processor. The logic is configured to cause the processor to perform a method which includes: computing a fingerprint of a data chunk, and determining whether a short term dictionary corresponding to the namespace comprises an entry corresponding to the fingerprint. In response to determining the short term dictionary does not comprise the entry, a determination is made whether a long term dictionary corresponding to the namespace comprises the entry. In response to determining the long term dictionary comprises the entry: the data chunk is written to the data store in the deduplicating manner, and the short term dictionary is repopulated with the entry. Moreover, in response to determining the long term dictionary does not comprise the entry, the data chunk is written to the data store in a non-deduplicating manner. |

Data operations using a cache table in a file system
Methods, systems, and computer storage media for providing reduced-latency data operations in a file system. In operation, a request to perform a data operation associated with a B+ table storage of a file system is received. The file system supports the B+ table storage that is accessible using a B+ tree lookup logic for accessing B+ table data and supports a cache storage that is accessible using a cache table lookup logic for accessing cache data in the cache storage. A number of references to the location in the B+ table storage is determined. The location in the B+ table storage is associated with the request to perform the data operation. Based on determining the number of references to the location, a cache storage location to perform the data operation is accessed. The cache storage location is mapped (using the cache table) to the location in the B+ table storage. |
