Fragmentation is a feature, not a "problem".

If all BTree blocks is 100% full, then every INSERT will cause a costly block split, and lead to blocks that are only 50% full.


Do not bother OPTIMIZEing InnoDB tables.,634129 (when is the proper time to execute optimize table command ?),627124 (How can I know the proper time of analyze time),619520 (fragmentation in innodb index),634146 (Deleted Records and Optimize),618481 (Execute table optimization concurrently),635519 (mysql server crashes on archive table),635342 (Problem with De-Fragment table)

Shall I beat the question to death some more?
