Vladimir Ozerov updated IGNITE-8841:
------------------------------------
Component/s: mvcc
> MVCC TX: Read transactions remap when coordinator fails.
> --------------------------------------------------------
>
> Key: IGNITE-8841
> URL: https://issues.apache.org/jira/browse/IGNITE-8841
> Project: Ignite
> Issue Type: Improvement
> Components: mvcc, sql
> Reporter: Roman Kondakov
> Priority: Major
> Labels: failover
>
> At the moment all read transactions are forcibly rolled back during
> coordinator change. It would be nice to remap it somehow until they locked a
> topology. For example, it is possible to obtain a new "write" mvcc version
> from the new coordinator and use this version for all further writes while
> using "old" version for reads. In this case we need to change visibility
> rules a little: "old" version should see "own" updates made by "new" "write"
> version.
