My question is - how to reuse space in Index Organized Table (IOT) after =
deleting substantial amount of rows.
When I deal with regular table, after deleting a lot of rows I rebuild =
the indexes in order not to leave gaps in the index blocks, because we =
know that this empty space in the indexes will not be reused (unlike, =
when it is reused in table blocks after PCTUSED threshold met in the =
block).
So, what could be done with IOT in order to prevent constant growth, =
even after a lot of rows being deleted?
