How to copy data from a large SharePoint Online list in Azure Data Factory (ADF)?

asnth 0

I am having trouble copying data from a large SharePoint Online list that has many records and columns in Azure Data Factory. I am unable to preview or copy the data, and I'm not sure if the issue is with the size of the list or the column types.

I've attempted to use the Query option to filter by modified date or select the Id column alone, but the operation times out. My Request timeout is set for 1 hour, but the data preview times out after a minute or so. I've successfully previewed and copied data with/without these queries from other lists on the site. Can anyone help? Thanks.

Hi @asnth
According to your description, this problem only occurs in specific SharePoint list. Please try to do a troubleshooting, check if the SharePoint Online data type is not supported with the OData data type.

@NIKHILA NETHIKUNTA how would I check if the data type was not one of the listed data types? Also, I still get the error when I am trying to return the Id column alone, which is supported.

Hello @asnth

There could be several reasons why you are unable to preview or copy the data, such as the size of the list, the column types, or the query you are using.

To troubleshoot this issue, I recommend the following steps:

Check the size of the list: If the list is very large, it may take a long time to preview or copy the data. You can try to limit the number of records returned by using the Query option to filter by modified date or select the Id column alone.

Check the column types: If the list contains columns with complex data types, such as lookup columns or managed metadata columns, it may cause issues with the data preview or copy operation. You can try to exclude these columns from the copy operation or use a different data type mapping.

Check the Request timeout: If the data preview times out after a minute or so, it may be due to the Request timeout setting. You can try to increase the Request timeout to a higher value, such as 2 hours, to see if it resolves the issue.

Check the network connectivity: If the issue persists, it may be due to network connectivity issues between Azure Data Factory and SharePoint Online. You can try to test the network connectivity by using a different tool, such as PowerShell or SharePoint Online Management Shell, to see if you can access the list data. If none of these steps resolve the issue, you may need to contact Microsoft Support for further assistance. I hope this helps! Let me know if you have any other questions.

I hope that this response has addressed your query and helped you overcome your challenges. If so, please mark this response as Answered. This will not only acknowledge our efforts, but also assist other community members who may be looking for similar solutions.

Hi @Pinaki Ghatak ,

Thanks for your reply. I have tried all of your suggestions but I am still experiencing the issue.

The list contains ~30k rows of data, and there are indeed several complex columns. I have tried to select the Id column and return 1 row of data ($select=Id&$top=1) and I receive an InternalServiceError. When the same query is ran on another list on the site, I can return data. In addition, I increased the request timeout to 2 hours.

There is no network connectivity issues as I can connect and copy from other lists on the site. In addition, I have used the SharePoint REST API to construct the URL using the same filters and I am able to view the data in my browser (https://<name>.sharepoint.com/sites/<sitename>/_api/web/lists/getbytitle('<LISTNAME>')/items?$top=1&$select=Id).

Kindly see the error message from ADF below:

Failure happened on 'Source' side. ErrorCode=ODataRequestNotSucceeded,'Type=Microsoft.DataTransfer.Common.Shared.HybridDeliveryException,Message=Requesting response from path LISTNAME and query $select=Id&$top=1 failed with status code InternalServerError and message <?xml version="1.0" encoding="utf-8" standalone="yes"?> <error xmlns="http://schemas.microsoft.com/ado/2007/08/dataservices/metadata"> <code></code> <message xml:lang="en-US">An error occurred while processing this request.</message> </error>.,Source=Microsoft.DataTransfer.Runtime.ODataConnector,'
