> Partition preloader must support cache partition file relocation from one
> cluster node to another (the zero copy algorithm [1] assume to be used by
> default). To achieve this, the file transfer machinery must be implemented at
> Apache Ignite over Communication SPI.
> _CommunicationSpi_
> Ignite's Comminication SPI must support to:
> * establishing channel connections to the remote node to an arbitrary topic
> (GridTopic) with predefined processing policy;
> * listening incoming channel creation events and registering connection
> handlers on the particular node;
> * an arbitrary set of channel parameters on connection handshake;
> _FileTransmitProcessor_
> The file transmission manager must support to:
> * using different approaches of incoming data handling – buffered and direct
> (zero-copy approach of FileChannel#transferTo);
> * transferring data by chunks of predefined size with saving intermediate
> results;
> * re-establishing connection if an error occurs and continue file
> upload\download;
> * limiting connection bandwidth (upload and download) at runtime;
