>             Project: Ignite
>          Issue Type: Bug
>            Reporter: Vladislav Pyatkov
>            Assignee: Vladislav Pyatkov
>            Priority: Major

> h3. Motivation
> Async IO is used by default to access a file system:
> {code}
>     /** Use an asynchronous file I/O operations provider. */
>     @Value(hasDefault = true)
>     public boolean useAsyncFileIoFactory = true;
> {code}
> This approach assumes that we read/write the file asynchronously (in the other threads) and then handle a result in the callback. Callbacks will be handled in the default thread pool if we do not determine it when a file channel opens.
> {code}
>     public AsyncFileIo(Path filePath, OpenOption... modes) throws IOException {
>         ch = AsynchronousFileChannel.open(filePath, modes);
>     }
> {code}
> h3. Definition of done
> Async IO callbacks should be handled in Ignite pool (create a new one or use one of the already existing ones).
