Delta Table Update

[ldas04]

A fact table saved as delta table using copy data activity in fabric from SQL database. An update is done on the fact table using spark SQL script in fabric. If I run the copy data activity again in the pipeline will the update retain in delta table? Explain the situation

Hi @ldas04 ,

Based on your description, your question is whether the updates will remain in the delta table if you run the copy data activity again in the pipeline.
As far as I know, updates will retain in the Delta Table after copying data again, provided that the data copying process is configured correctly.
