      Description

      The attached design doc proposes a standard interface for block transferring, which will make future engineering of this functionality easier, allowing the Spark community to provide alternative implementations.

      Block transferring is a critical function in Spark. All of the following depend on it:

      • shuffle
      • torrent broadcast
      • block replication in BlockManager
      • remote block reads for tasks scheduled without locality
