Recently in a project where we need to work with large lists, as you will know, in SharePoint, lists with more than 5000 items causes problems to the users, and lists with more than 20k items are not possible to manage by the admins, in that cases you will receive a problem like:
“The view can not be displayed because it exceeds the list view threshold(5000 items) enforced be the administrator”
But if you look into the logs, you’ll see the following:
Microsoft.SharePoint.SPQueryThrottledException: The attempted operation is prohibited because it exceeds the list view threshold enforced by the administrator. —> System.Runtime.InteropServices.COMException: The attempted operation is prohibited because
In this case, it was a news list, so it was not possible to order the list in folders or any other method to avoid the item threshold limitation. What is the problem? This issue is By Design, so the throttling limit is enforced to protect the SharePoint Server, why? because each time we access to that list we make a SQL query as the number of items that this list has, so in case that this query exceeds 5000 items (by default) this action is avoided.
As you’ll know, it is possible to change this limit, but you’ll change this limit to the entire web app, which is not recommended, so why we can do as a workaround? Disable throttling 🙂 But you have to take into account that disabling throttling will cause performance issues on the SharePoint Server or the SQL Server.
$web= get-spweb “url”
$list.enablethrottling = $false
After doing this, you’ll query more items in that list 🙂
hope that helps!
