---------------------------------------
Summary: 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
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.
