  • RE: disc read latency for mdf/ndf data files

    Generally, you prefer 10ms or less, although up to 20ms is ok. Anything over that is poor and progressively getting worse, of course.

    Again, in general, 100ms is not acceptable,...

  • RE: Policy Based Management - Enabling Transaction Logs

    Yeah, I'm completely lost as to what the code is trying to code. And if the db is offline, you won't be able to access the view "sys.database_files" within...

    Hi Scott,

    Lynn Pettis (7/24/2014)

    INNER JOIN MyLinkedServer.SandBox.dbo.AnotherTable myAlias

    ON MyTable.ID = MyAlias.ID

    WHERE myAlias.CustomerID = 12

    Hi ,

    Identity as a clustered index was not my first choice. The problem is that this is a high volume, high concurrency OLTP with thousands of data inserts per minute....

  • RE: Question on data compression

    If you're willing to push back against the myth that identity should be default clustering key, and base the clustering key(s) choice on data instead, you can change the bolded...
