https://community.appian.com/discussions/f/general/18394/bulk-data-validation-using-integrationsHi Team, I have a requirement to upload the excel and read the entries to populate the data into the appian database. while reading the data i need to check the valid data from integrations. For each and every row i need to call 2 integration to checken-USTelligent Community 12https://community.appian.com/thread/72420?ContentTypeID=1Tue, 03 Mar 2020 10:43:10 GMTd3a83456-d57b-489c-a84c-4e8267bb592a:c4081174-ad3c-471f-8e5a-3db1947c81a3Stewart Burchell<p>From your description it sounds like you have a good handle on the sorts of issues that need to be addressed. The main thing is to ensure that you have means of &quot;throttling&quot; the processing so that you don&#39;t flood the application server with process instances (which, again, sounds like you&#39;ve recognised and have a design in mind to pre-empt this).</p> <p>Some questions about the nature of the validation integrations:</p> <ul> <li>do they have to be integrations? that is, is there any way to bring the logic/data into Appian so that this can be conducted locally? That would definitely improve the performance, but may bring other issues to solve (e.g. keeping the Appian versions in sync)</li> <li>do they have to be called at the individual row level? That is, could the integrations take batches of data, and so reduce the&nbsp;number of calls you have to make?</li> <li>similarly, is there any middle-ware in the architecture that could make the two calls for you, so that you reduce the number of calls from Appian to just one per row?</li> </ul><div style="clear:both;"></div>
