Folks, can you take a look at my changes?
All of them are quite safe to be part of Ignite's source code. There no changes
among Ignite's critical sections.
I'd like to finish with these changes and proceed with the next one -
IGNITE-11073 to make progress with the file based rebalance (IEP-28).
> Add support files transmission between nodes over connection via
> CommunicationSpi

> Key: IGNITE-10619
> URL: https://issues.apache.org/jira/browse/IGNITE-10619
> Project: Ignite
> Issue Type: Sub-task
> Components: persistence
> Reporter: Maxim Muzafarov
> Assignee: Maxim Muzafarov
> Priority: Major
> Labels: iep-28
>
> 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;
