摘要： A method and system for increasing server cluster availability by requiring at a minimum only one node and a quorum replica set of replica members to form and operate a cluster. Replica members maintain cluster operational data. A cluster operates when one node possesses a majority of replica members, which ensures that any new or surviving cluster includes consistent cluster operational data via at least one replica member from the immediately prior cluster. Arbitration provides exclusive ownership by one node of the replica members, including at cluster formation, and when the owning node fails. Arbitration uses a fast mutual exclusion algorithm and a reservation mechanism to challenge for and defend the exclusive reservation of each member. A quorum replica set algorithm brings members online and offline with data consistency, including updating unreconciled replica members, and ensures consistent read and update operations.
摘要翻译：通过至少要求一个节点和副本成员的仲裁复制集来形成和操作集群，来提高服务器集群可用性的方法和系统。副本成员维护集群操作数据。当一个节点拥有大多数副本成员时，集群就会运行，从而确保任何新的或存活的集群通过至少一个来自紧接在前的集群的副本成员包括一致的集群操作数据。仲裁提供复制成员的一个节点的独占所有权，包括在集群形成时以及所有节点出现故障时。仲裁使用快速互斥算法和保留机制来挑战和保护每个成员的独家保留。仲裁复制集算法使成员在线和离线具有数据一致性，包括更新未协调的副本成员，并确保一致的读取和更新操作。

摘要： In one embodiment, a method includes accessing data identifying a video for processing and mapping an instruction graph to the video based on one or more predetermined criteria and the data identifying the video. The instruction graph describes a workflow for processing the video, and the workflow includes a series of services that each provide particular processing of the video. The method includes calling the services in series to process the video based on the instruction graph. The video streams to each service in series as the video processes. A downstream service may begin processing one or more portions of the video after an upstream service has finished processing the one or more portions of the video and before the upstream service has finished processing the video in its entirety.

摘要： A system and method provides transcoding a video in parallel by multiple transcoders based on a measure of video coding complexity (VCC). The system has a video pre-processing module, a master transcoder, a transcoding controller and multiple transcoders. The video pre-processing module transcodes a source video into an intermediate video. The master transcoder partitions the intermediate video into multiple transcoding units, where a transcoding unit identifies a portion of data of the intermediate video for transcoding. The master transcoder further generates a transcoding request for each transcoding unit. The transcoding controller distributes the transcoding units to the multiple transcoders, which transcode the data of the transcoding units in parallel into transcoded data.
摘要翻译：基于视频编码复杂度（VCC）的测量，系统和方法通过多个代码转换器并行地对视频进行代码转换。该系统具有视频预处理模块，主代码转换器，代码转换控制器和多个代码转换器。视频预处理模块将源视频转码为中间视频。主代码转换器将中间视频分割成多个代码转换单元，其中代码转换单元识别用于代码转换的中间视频的一部分数据。主代码转换器还为每个代码转换单元生成代码转换请求。代码转换控制器将代码转换单元分配给多个代码转换器，其将代码转换单元的数据并行转码为代码转换的数据。
