Clock compensation for streaming media systems
In one embodiment, systems, methods and non-transitory machine readable media detect differences between the rate of production, by a server, of media segments identified in an HTTP compliant playlist and the rate of consumption, by a client device, of the media segments in streaming media content. These differences, once detected, can be used to adjust a playback rate at the client to reduce the difference between the server rate and the client rate. This detection can be used in low latency streaming media contexts in which the client device is playing back content that is live, such as a live sports event happening during the playback by the client device. The adjustment of the client's playback rate can avoid running out of buffered media segments (when the client's rate is much faster than the server's rate) and can avoid increasing latency at the client device and overloading a buffer with too many media segments (when the client's rate is much slower than the server's rate). |

Stream-based data deduplication using directed cyclic graphs to facilitate on-the-wire compression
Stream-based data deduplication is provided in a multi-tenant shared infrastructure but without requiring “paired” endpoints having synchronized data dictionaries. Data objects processed by the dedupe functionality are treated as objects that can be fetched as needed. As such, a decoding peer does not need to maintain a symmetric library for the origin. Rather, if the peer does not have the chunks in cache that it needs, it follows a conventional content delivery network procedure to retrieve them. In this way, if dictionaries between pairs of sending and receiving peers are out-of-sync, relevant sections are then re-synchronized on-demand. The approach does not require that libraries maintained at a particular pair of sender and receiving peers are the same. Rather, the technique enables a peer, in effect, to “backfill” its dictionary on-the-fly. On-the-wire compression techniques are provided to reduce the amount of data transmitted between the peers. |

If not pending checkpoint exists, new data records may be retrieved, processed, and sent from the partition of the data stream to a specified destination. If a checkpoint is pending, then the data records identified by the checkpoint metadata as pending may be retrieved, processed, and sent to the specified destination. |
