> Deadlock in transactions started by IgniteToIgniteCdcStreamer
> -------------------------------------------------------------

> Key: IGNITE-23388
> URL: https://issues.apache.org/jira/browse/IGNITE-23388
> Project: Ignite
> Issue Type: Bug
> Reporter: Maksim Timonin
> Assignee: Maksim Timonin
> Priority: Major
> Labels: ise
> Fix For: 2.17
>
>
> IgniteToIgniteCdcStreamer collects changes in batch size (configured with
> maxBatchSize). Then all updates put to target cluster with `putAllConflict`.
> This call creates transaction that covers all entries, primary and backups.
> Then 2 streamer on different nodes might have crossing set of entries
> (primary and backups). The set is not ordered and inserted as ordinary
> HashMap. It leads to deadlock.
