mariadb/storage/connect/catalog.h
Olivier Bertrand 74a4672622 - Move DataPath from the MYCAT catalog to the ha_connect handler. Indeed
it belongs to each tables and the catalog being share between several
  instances of CONNECT, when a query implied several tables belonging to
  different databases, some where pointing on the wrong database. This
  fix bugs occuring in queries such as:
  INSERT into db1.t1 select * from db2.t2;
  Where the t1 data file was made in db2.
