fragment_count

  • Dear All

    Can somebody explain about fragment_count

    Regards

  • A Fragment is a collection of pages in sequence

    For example you can have data spread across 6 pages, but these pages are located in different extents :

    Fragment 1 Fragment 2 Fragment 3

    page 1, page 2, page 3 page 11, page 12 page 18

    Hope this was helpful.

  • Hi

    Thanks Jonysuise and Bhuvnesh

    I was reading about index fragmentation, thats when came across fragment_count. And could no understand the defiantion on the msdn site. So if you can elaborate what it is exactly then it will be great.

    What does fragment_count 2000 means? is it in proportion to fragmentation %?

    Regards

  • fragment count 2000 means that index data is spread accross 2000 blocks of consecutive pages.

  • In general, ignore it. It was part of Microsoft's (failed) attempt to simplify the fragmentation information
