> DML: improve deadlock handling
> -------------------------------
>
> Key: IGNITE-7984
> URL: https://issues.apache.org/jira/browse/IGNITE-7984
> Project: Ignite
> Issue Type: Task
> Components: sql
> Affects Versions: 2.4
> Reporter: Vladimir Ozerov
> Assignee: Vladimir Ozerov
> Priority: Major
> Fix For: 2.5
>
>
> Current DML implementation is not transactional. It groups keys in batches by
> their affinity, and then flushes that batches synchronously. This could lead
> to deadlocks easily.
> This could be improved if we sort key within a batch. However, this would
> require new comparison function for {{BinaryObjectImpl}}, as it is not
> comparable.
