This script analyzes the design and performance of your indexes.

To learn more, visit http://FirstResponderKit.org where you can download new
versions for free, watch training videos on how it works, get more info on
the findings, contribute your own code, and more.

Known limitations of this version:
 - Only Microsoft-supported versions of SQL Server. Sorry, 2005 and 2000.
 - The @OutputDatabaseName parameters are not functional yet. To check the
   status of this enhancement request, visit:
   https://github.com/BrentOzarULTD/SQL-Server-First-Responder-Kit/issues/221
 - Does not analyze columnstore, spatial, XML, or full text indexes. If you
   would like to contribute code to analyze those, head over to Github and
   check out the issues list: http://FirstResponderKit.org
 - Index create statements are just to give you a rough idea of the syntax. It includes filters and fillfactor.
 --        Example 1: index creates use ONLINE=? instead of ONLINE=ON / ONLINE=OFF. This is because it is important 
           for the user to understand if it is going to be offline and not just run a script.
 --        Example 2: they do not include all the options the index may have been created with (padding, compression
           filegroup/partition scheme etc.)
 --        (The compression and filegroup index create syntax is not trivial because it is set at the partition 
           level and is not trivial to code.)
 - Does not advise you about data modeling for clustered indexes and primary keys (primarily looks for signs of insanity.)

Unknown limitations of this version:
 - We knew them once, but we forgot.
