Files are divided into parts and at least some of the parts are transmitted to a client using a communication channel. At least some of the transmitted parts are cached locally. This allows subsequent streaming playback of the file while using less bandwidth by transmitting the part of the file that hasn't been cached, and combining the cached parts with the transmitted parts. In some embodiments, files may be represented at a low quality level by a first data set, and at higher quality levels with additional data sets. Data sets are cached locally, so that during subsequent streaming playback of the file, the quality level of the playback may be improved by sending additional data sets using bandwidth that would otherwise be dedicated to transmitting the cached data sets.

A centralized resource distribution is described where the decision portion of partitioning data among cluster nodes is made centralized while the actual mechanics to implement the partitioning remain a distributed algorithm. A central distribution coordinator is used to create an extensible central strategy that controls how the data will be partitioned across the cluster.

For example, in accordance with the distributed algorithm, one node may decide that it needs to obtain a particular partition in light of the central strategy and carry out the necessary steps to obtain that data, while other nodes may be asynchronously performing other individual partition transfers relevant to those particular nodes.
