For one our Telecom client we need to Import the data (approx. 8 Million records) into New SNOW Instance into 4 different Tables. 

 

can External ETL Tools directly insert data into ServiceNow?

 

Please reach out to me if you need any further Details ?

 

Thanks

Yes, external ETL tools can insert data directly into ServiceNow, usually via the REST API, SOAP API, or direct JDBC integration (though JDBC is more limited and not recommended for inserts).

A few things to keep in mind:

  • Use ServiceNow Import Sets if possible—they help manage large volumes safely.

  • For 8M+ records, consider batching and asynchronous processing to avoid performance issues.

  • Tools like MuleSoft, Dell Boomi, Informatica, or even custom Python scripts with REST work well.

  • Make sure to throttle API calls to respect SNOW rate limits.

If you’re using MID Server or IntegrationHub, you can also streamline secure data transfers.
