> ------------------------------------------------------------------------------
>
> Key: IGNITE-17434
> URL: https://issues.apache.org/jira/browse/IGNITE-17434
> Project: Ignite
> Issue Type: Improvement
> Components: sql
> Affects Versions: 3.0.0-alpha5
> Reporter: Evgeny Stanilovsky
> Priority: Major
> Labels: ignite-3
>
> After [1] was implemented, there are some improvements seems still required:
> # If no explicit tx is specified it`s possible to obtain situation when keys
> from one bulk enlisted under different tx [2]
> # Implicit tx (not tx at all but tx meta - timestamp, first enlisted
> partition and so on ..) need to be replicated into all calcite execution
> fragments.
> Thus in [3] seems we need to start implicit tx if no explicit defined and
> correctly process it in [4]
> [1] https://issues.apache.org/jira/browse/IGNITE-17328
> [2] ModifyNode#flushTuples
> [3] ExecutionServiceImpl#executeQuery
> [4] DistributedQueryManager#execute
