Re: [libreoffice-users] Re: [MariaDB Announce] MariaDB 5.5.30 now available

Dan,
That is another issue.  It is good that you were able to get MySQL back 
when you needed it.  I think what I read was that Mariadb changed the 
database itself somehow, making it incompatible with MySQL.  Thus, all 
the work done on it with Mariadb was lost from the last MySQL-compatible 
database backup.  That is scary - lost data.

I just went searching again for where I read this caveat and came up 
with this posting by "ppr:kut" to LinuxQuestions.org on 1-31-13:

   "I'm not sure what problems you imagine, but I'm not aware of any
   issues. You wouldn't be able to switch easily from MariaDB back to
   MySQL once you start using MariaDB specific features, but that's
   clear from the start."

You can find this message and others on:

   
http://www.linuxquestions.org/questions/slackware-14/replace-mysql-with-mariadb-in-slackware-4175447832/

Now that I read it again, it sounds like they might be talking about 
Mariadb user features, not database compatibility.  Kind of like someone 
who moves from msoffice to LO can't go back because they like the LO 
features.  I would like to know if anyone has tried to go back to MySQL 
from using Mariadb and how *physically* successful it was.
Sorry about the confusion.
Girvin
