hi, Chris
I'm sure it will, what makes you think it won't?
Because some paper say that when the row is deleted or update, Innodb
just make a mark that the row is deleted and it didn't delete the
rows. I can't find more information about the re-use tablespace. Can
you give me more?

hi, Chris
Thank you for your advice!
I know that Innodb use the logfiles circularly. Can Innodb re-use the
deleted rows' disk space in tablespace?

You might need an 'optimize table' or something to see a reduction in
the on
of innodb.
Try this it might help u out.

I think I know the fact: The Innodb can't reuse the deleted rows' disk
space. And a solution is: dump the data; shutdown mysql; delete the
files; restart mysql; import the data.
InnoDB does re-use the space inside the database, it's the
the space usage of innodb.
Try this it might help u out.

Hi, all
I know the Innodb use MVCC to achieve very high concurrency. Can
Innodb reuse the deleted rows disk space? I have an database which
have many update operation. If Innodb can't reuse the space of deleted
rows, I worry about that MySQL will exhaust our disk space very
quickly
