I'm trying to use SharePoint rest API to get items from a SPO list. It has around 15K items. But I'm using filters and expecting less than 30 items in the result. It works fine when normal columns are used for filtering. But when I use people picker column, it throws the below error:

    <m:error xmlns:m="http://schemas.microsoft.com/ado/2007/08/dataservices/metadata">
<m:code>-2147024860, Microsoft.SharePoint.SPQueryThrottledException</m:code>
<m:message xml:lang="en-US">The attempted operation is prohibited because it exceeds the list view threshold.</m:message>

Below is the query I used:

https://test.sharepoint.com/sites/SiteName/_api/web/lists/getbytitle('ListName')/items?$select=ID,Employee/EMail,Employee/Title,Employee/JobTitle,Employee/Department&$expand=Employee/Id&$filter=(Employee/email address removed for privacy reasons%27)

Could anyone help me fix this issue?

Indexing the affected column may help you, for more information check out Microsoft's support article on managing large lists:

Manage large lists and libraries

  • The column is already indexed.

  • Is the person column single value or multi value? Jul 22, 2022 at 15:45
  • It's a single value column.

  • Strange, documentation suggests that it's a supported column type for indexing. Have you tried only returning/selecting that people column in your query? Jul 22, 2022 at 15:54
  • _api/web/lists/getbytitle('listname')/items?$select=Employee/EMail&$expand=Employee&$filter=(Employee/EMail eq '[email protected]') - tried this and it did not work.

This is the fastest set-up I’ve got, & I’ve got it filtering on non-indexed columns with the HTTP call because I have a preceding ID filter limiting things to 5000 or less items per call before the other filters & it is within an Apply to each concurrently running for each batch of 5000 across the entire dataset. But it still takes 1-4 seconds with the kind of query you describe. https://powerusers.microsoft.com/t5/Community-App-Samples/Large-SP-List-Delegation-Workaround-App/td-p/2330721
