> {{org.apache.ignite.internal.client.thin.TcpClientChannel#send}} creates a buffer copy, because the buffer will be returned to the pool upon leaving the scope, but we need it to survive longer while NIO framework processes it.
> However, for synchronous requests we block the thread anyway, so an extra copy can be avoided. See discussion in [#8483|https://github.com/apache/ignite/pull/8483#discussion_r533915757]
