    Bug#12595091 POSSIBLY INVALID ASSERTION IN BTR_CUR_PESSIMISTIC_UPDATE() · a5ddcaab
    Marko Mäkelä authored
    Facebook got a case where the page compresses really well so that
    btr_cur_optimistic_update() returns DB_UNDERFLOW, but when a record
    gets updated, the compression rate radically changes so that
    btr_cur_insert_if_possible() can not insert in place despite
    reorganizing/recompressing the page, leading to the assertion failing.
