Abstract: In some embodiments, during synchronizing of files in a source data set to a destination data set, a method receives a set of events that occurred at the source data set after replicating an image of the source data set to the destination data set. The method analyzes the set of events to determine if an exception to a first set of rules for performing a set of operators on the destination data set for the set of events occurs. A second set of rules for the exception is selected based on analyzing the set of events. The method processes the set of operators for the set of events according to the second set of rules to synchronize data from the first data set to the second data set based on the set of events. The processing of the set of operators uses the second set of rules.

Abstract: In some embodiments, a method receives a request for a video and receives a ranking of content delivery networks for the request. Also, global constraints are received for the content delivery networks. The global constraints define an allocation for respective content delivery networks. The method selects a content delivery network using the global constraints and the ranking. A score for the content delivery network is altered from a first score to a second score in the ranking and used in the selecting of the content delivery network. The content delivery network that is selected for the request is outputted.

Abstract: In some embodiments, a method receives a plurality of video segments of a video using a plurality of computing instances and measures data received for the plurality of computing instances during a time window. A video segment for a computing instance in the plurality of computing instances is not fully downloaded during the time window. The method calculates a video delivery metric for the plurality of computing instances based on the data received and calculates an evaluation measurement based on the video delivery metric. The evaluation measurement is used to control an addition or a termination of a computing instance.

Abstract: In some embodiments, a method receives a history of videos that were viewed on a video delivery system as a first sentence in a sequential order and a target video as a second sentence as input to a prediction network. The prediction network analyzes representations for the history of videos and a representation of the target video. The prediction network generates a session representation based on bidirectionally analyzing a sequence of the first representations and the second representation. The method uses the session representation to determine whether to recommend the target video.

A distribution area is defined by one or more geographic primitives and associated with a distribution area identifier. A geographic primitive is defined by one or more location identifiers. The method determines whether the one or more geographic primitives of the media content is applicable to a geographic primitive that is determined from a location identifier associated with a request.

Abstract: In some embodiments, a method receives a first ranking of content delivery networks for a playback session of a video and receives global constraints for the content delivery networks. The global constraints define an allocation for respective content delivery networks. The method alters a score for a content delivery network in the first ranking to generate a second ranking of content delivery networks. Then, a content delivery network is selected from the second ranking for the playback session of the video.

Abstract: In one embodiment, a method receives a first stream identifier for a video stream. The first stream identifier is received in a request from a client for the video stream. The method selects a virtual stream identifier for the first stream identifier where the virtual stream identifier is associated with a plurality of physical stream identifiers associated with a plurality of physical streams. A ranking of the plurality of physical stream identifiers is analyzed to select one of the physical stream identifiers. Then, the method outputs the one of the physical stream identifiers as the video stream to use in response to the request for the first stream identifier. The one of the physical stream identifiers is sent to the client to allow the client to request the respective physical stream.

Abstract: In some embodiments, a method receives a first set of video files at a node that delivers video files to client devices and receives a second set of video files. The second set of video files are predicted to be delivered by the node to a client device during a time period. The node receives a request for a video file from a client device and determines whether the video file is stored in the first set of video files and the second set of video files. When the video file is stored at the node, the node sends the video file from the first set of video files and the second set of video files. When the video file is not stored in the first set of video files and the second set of video files, the node sends a request for the video file to another node.

Abstract: In some embodiments, a method receives a first textual description of content and converts the first textual description of content to a first image representation. The method compares a similarity between the first image representation and a second image representation for candidate metadata. The candidate metadata is associated with a second textual description of content. The method determines whether the first textual description of content is associated with the second textual description of content based on the comparison of similarity of the first image representation and the second image representation.

Abstract: In some embodiments, a method selects a sequence of programs watched by a user account. The method calculates a first set of weights based on comparing content of the sequence of programs to content of a target program and calculates a second set of weights based on an order of the sequence of the programs and the first of weights. The first set of weights and the second set of weights are applied to the sequence of programs to generate a prediction of a similarity of the sequence of programs to the target program. Then, the method outputs the prediction of the similarity for use in determining a recommendation for the user account.
