Slow ExecuteMultiple update

(0) ShareShare

Posted on by kranis 155

I´m trying to update one field on 300,000 contact records in MS CRM. I´m using the standard way to update:

responses = (ExecuteMultipleResponse)orgService.Execute(requests);

However, the problem is that it´s really slow. To update 1000 records it takes approx 3 minutes 20 sec.
And often I get timeout exceptions, which I need to handle in code.

There is no plugins triggering on the field i´m updating. Been trying both on On-premise 2016 and CRM Online.

Is this delay normal? What can I do?

(Retrieving data is much faster. I´m able to fetch approx. 3.5millon records within 1.5 hour).

    Hi kranis,

    If you post your full code, we can suggest improvements to it.

    Hi, Give a try with multi-threading

    I'd create a small c# application with the Dynamics 365 libraries and run a parallel update. This is a very old article, but it describes the principles behind such a solution: blogs.msdn.microsoft.com/.../parallelism-using-parallel-for-with-the-crm-sdk

    With this you would be able to try/catch/continue on any eventual exceptions as well.

    In which way is it similar to multiple threading concept would you say?

    Hi,

    I used ExecuteMultiple. Never came across to the situation where I need to update huge data like your case. It will be great to see your experience with Web api bulk update. Thinking it should be fine.

    Thanks,

    Anand

    Hi, Thanks for the reply!. I can try that. What is your experience with Web api bulk update? How long does it take to update for e.g. one batch of 1000 records?

    Hi,

    Would you give a try with batch functionality in the Web API for bulk update?

    Check below reference

    No workflows running when updating the contact. (I´m not creating records, only updating)

    Thank you for your reply. I turned auditing off. But no difference unfortunately.
