MySQL性能-删除表行或仅将列标记为已删除

Question

I've read a few times that for performance reasons you best not to delete rows in a table but rather use a column to mark the rows as deleted.

eg: I have a table that holds members photos and when I member removes a photo I currently delete the row. I could instead just mark the photo as deleted but leave it in the table.

So rather then run a DELETE I would run a UPDATE.

Is this really a better way to use MySQL INNODB Tables or does it really not make any difference?

Answer 1

If you need to preserve the data and history set a field to DELETE otherwise removed the row from your table. No point using disk space, for data you don't need.
