innodb_defragment_fill_factor_n_recs

How many records of space defragmentation should leave on the page. This variable, together with innodb_defragment_fill_factor, is introduced so defragmentation won't pack the page too full and cause page split on the next insert on every page. The variable indicating more defragmentation gain is the one effective.
