Re: split rows

Ok, well very much like Oracle and even standard file systems, MySQL will try to fill empty gaps in the table data file as it goes, and when a row does not fit within a single gap a pointer is made to the remaining part of the row. OPTIMIZE cleans this up and places all the rows into the data file one by one so that no rows are split up. From and end user point of view there is no real difference in accessing the rows and I don't recall a way to get the amount of fragmentation from the server in a human readable form.
