Greetings Tomas.
Right now CS uses actual version of MDB but with some additions to speed up analitics. One of this features doesn't allow you to change session optimizer flags but the flags for InnoDB-only queries are as global ones. To continue with your issue I suggest you to start a discussion in our Google Group at https://groups.google.com/forum/#!forum/mariadb-columnstore. Plz add the overview of the procedures you use to move data from innodb to columnstore together with explain plans for innodb only queries.
