> Project: Ignite
> Issue Type: Improvement
> Components: sql
> Affects Versions: 3.0.0-beta1
> Reporter: Evgeny Stanilovsky
> Assignee: Pavel Pereslegin
> Priority: Major

> Fix For: 3.2

>
> 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.
