      Description

      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;
