 Description   

After the primary (node 1) in a cluster is killed and then restarted , we have a discrepancy between MXS showing node 2 as primary and MCS showing node 1 as primary .

The details are in https://mariadbcorp.atlassian.net/wiki/spaces/~695761903/pages/1629783457/CMAPI+primary+mismatch+observation

and in

https://jira.mariadb.org/browse/MCOL-4939

The problem goes back to mariadb/skysql-enterprise-columnstore:sky-5.5.2-1-GA

from last June

More on the subject . It turns out that after some wait (1-2 min) the MCS switches the primary to match MXS.

Unless there are objections , I will cancel the Jira tomorrow
