    Description

      To unconditionally push all queries that contain InnoDB tables and don't contains MCS tables to MCS runtime one has to set variable columnstore_innodb_queries_use_mcs to true in the MDB configuration. This variable becomes active only on restart of the MCS plugin.
      MCS plugin during its init checks for the variable and sets create_select of Innodb handler to columnstore_init_func forcing MCS SelectHandler to be used by innodb.
