> Case: _Fragment is sent to worker node but no response Is obtained and 
> NodeLeft event is triggered. No information is available about fragment 
> execution progress here, but we know that no data is passed from such a node._
> 1. In case of RO Tx only this fragment(s) can be remapped if no rows have 
> been sent to the client, for example some kind of aggregate query (we have no 
> such mechanisms for now) .
> 2. Implicit RW tx - tx need to be rolled back, execution must be restarted 
> from the mapping phase.
> 3. Explicit RW tx - not recoverable. Need to close cursor with informative 
> exception.
