Re: To developers: If Maria engine does ZERO-VALUE-COMPRESSION ..
When ROW_FORMAT=DYNAMIC Maria behaves exactly as MyISAM does, and
http://bugs.mysql.com/bug.php?id=30824 applies.
When ROW_FORMAT=PAGE, Maria also does zero-value compression, but it reserves a bit of a space on every page to allow records to grow without overflows. That is, in many cases the record length can be increased without causing a fragmentation. And when the overflow happens the tail of the record is placed on a special overflow page with other record tails, and the record, again, can continue grow without being split in more fragments.
