hidden primary keys

InnoDB/XtraDB has always a primary key. When there is no explicit primary key there will be an implicit one (the hidden primary key).

So it seems to me there is no problem for XtraDB, isn't it?

Re: hidden primary keys

InnoDB/XtraDB uses a 6 bytes clustered index that is invisible to the user. But Galera needs an explicit primary key.
