摘要： This application discloses a shard adjustment method, apparatus, and device for a time series database, and a readable storage medium, and belongs to the field of data processing technologies. The method includes: First, feature information of an access request of at least one user for a data table of a time series database is obtained, where the feature information is used to reflect an access habit of the at least one user for the data table. The data table is divided into a plurality of shard groups according to a predetermined rule, and each shard group can be further divided into a plurality of shards. Each shard group is set in a different time period, and each shard is set in a different node. Then, the predetermined rule is adjusted based on the feature information, and a new shard group and/or a new shard that match/matches the access habit are/is generated according to an adjusted rule. In this application, a sharding rule can be updated in time based on feature information, to avoid occurrence of an exception caused by an improper sharding rule, so that a shard group and/or a shard match/matches an access habit of a user, and read/write performance of a node is ensured.

摘要： A method includes receiving a request to perform a shuffle operation on a data stream, the request including a set of initial key ranges: generating a shuffler configuration that assigns a shuffler from a set of shufflers to each of the initial key ranges; initiating the set of shufflers to perform the shuffle operation on the data stream; analyzing metadata statistics to determine whether a shuffler configuration update event occurs, the metadata statistics produced by the set of shufflers during the shuffle operation and indicating load statistics for each shuffler in the set of shufflers; and upon occurrence of the shuffler configuration update event and during the shuffle operation, altering the shuffler configuration based at least in part on the metadata statistics to produce an assignment of shufflers to key ranges that is different from the assignment of shufflers to the initial key ranges.

摘要： The formulation of a merged sorted list from multiple input sorted lists in multiple phases using an array pair. Initially, the first array is contiguously populated with the input sorted lists. In the first phase, the first and second input sorted lists are merged into a first intermediary merged list within the second array. Each subsequent phase merges a prior intermediary merged list resulting from the prior phase and, a next input sorted list in the first array to generate a next intermediary merged list, or a merged sorted list if there or no further input in the first array. The intermediary merged lists alternate between the first array and the second array from one phase to the next phase.

摘要： A media data encryption method and apparatus, and a media data playback method and system. The media data encryption method comprises : obtaining media data to be encrypted and a display screen structure parameter of a data playback end; constructing a data arrangement table corresponding to the display screen structure parameter; performing a data rearrangement operation on the data arrangement table to obtain position rearrangement index data representing a mapping relationship between a logic and a physical position of a display pixel; and according to the position rearrangement index data, performing pixel rearrangement encryption on each image frame of the media data to be encrypted to obtain encrypted media data. The media data playback method comprises : a data encryption end encodes and encrypts media data to be encrypted by adopting a media data encryption method to obtain a media data encrypted packet, and sends the media data encrypted packet to the data playback end; a receiving card of the data playback end decrypts the media data encrypted packet to obtain configuration data and media data to be decrypted, and configures a programmable logic circuit according to the configuration data to decrypt and play the media data to be decrypted.

摘要： System and method for establishing secure conference calls. In one example system, a central conference call server establishes point-to-point connections with accessory devices comprising a secure element and connected to corresponding participant devices. The conference call server includes an interface to a plurality of secure elements configured to perform scrambling and unscrambling of media signals communicated to and from the accessory devices. In another example, one of the participant devices operates as the central conference call server. In other examples, participant devices communicate on a conference call via point-to-point connections between all accessory devices connected to the participant devices. The accessory devices include secure elements for decryption and encryption of media signals communicated between the accessory devices.
