unknown 6ba273731d NDB temporary tables.
Temporary tables are not written to disk by DDL operations. This makes
DDL much faster (useful for tests), but tables are lost after system
restart.

New commit, since this feature will not be available in 5.1.


storage/ndb/include/kernel/signaldata/CreateIndx.hpp:
  Add new error messages for temporary tables.
