> Key: IGNITE-3479
> URL: https://issues.apache.org/jira/browse/IGNITE-3479
> Project: Ignite
> Issue Type: Task
> Components: cache
> Reporter: Alexey Goncharuk
> Assignee: Semen Boikov
> Fix For: 2.4
>
>
> Current transaction ID will not work for SQL MVCC ordering because two
> transaction IDs are not in total order across the cluster.
> One of the approaches is to have a dedicated coordinator which will assign a
> continuously growing transaction ID for each committed transaction. This ID
> must be acquired by each transaction at the last step of PREPARE stage.
