How to do incremental refresh in data pipeline?

Charlotte_chum — Tue, 18 Mar 2025 01:16:54 GMT

Hi all,

I would like to perform a 24-hour incremental refresh based on the last modified data. I found some details from online sources and Microsoft documentation, but I am unable to find specific information for data pipelines. Does anyone know how to do this?

Can you be more specific what you mean by incremenatl refersh in data pipelines?
Do you mean incremental data sync from a source to sink via copy activity?

Hi Charlotte_chum

Thank you for reaching out to the Microsoft Fabric Community Forum.

To implement a 24-hour incremental refresh in a Data Pipeline based on the last modified data, consider the below steps:

Make sure you have a source table with a LastModifiedTime column (datetime) to track changes, and a watermark table to store the last successfully processed timestamp.

Required a destination (e.g., Lakehouse or SQL DB) and access to Microsoft Fabric Data Factory to build and run the pipeline.

Create a pipeline parameter, e.g., LastRunTime, that will dynamically retrieve the last watermark value from watermark_table. Use the watermark in your SQL query to filter records modified in the last 24 hours.

Add a copy data activity in a pipeline, after successful data load, update watermark_table with the current UTC timestamp to record the latest successful run.

Use triggers in the Data Factory to schedule the pipeline to run every 24 hours.

For more detailed information, Please refer to the Microsoft official document:
