Issue with MERGE INTO for first batch

Joe1912
New Contributor III

I have source data with multiple rows and columns, 1 of column is city. 

I want to get unique city into other table by stream data from source table. So I trying to use merge into and foreachBatch with my merge function.  My merge condition is : On source.city = target.city. But then I realized that, in first batch, I will always get duplicated data becauce there is no data on target and duplicated city on first batch of source.

How can I resolve this ? thank you for supporting
