Will be nice to see on-line defragmentation feature of database pages.
now in working database - pages are allocated when new data are inserted
e.g we insert data to table A then we insert data in table B and once again some portion of data to table A
and when new pages are allocated we have some pages of table A then some pages of table B and once again some pages of table A
after few days pages of tables and indexes are totally fragmented
because of that when we read data from some table we have a lot of disk head move
will be a nice to have possibility to defragment database pages without taking database off-line
