SQL Server Change Data Capture update records but __$operation is 1, 2

  • Hi, today I found very strange case in CDC (Change Data Capture) table, we updated one record for several different columns, but in CDC table

    the __$operation is 1 , 2 and pk(pk_placement...) is the same. Normally __$operation should be 3,4, and pk is same. (And 1,2 means delete and insert.) I am not sure what's reason cause CDC using 1 and 2, it never happened before. At that time we have index rebuilt job for that table running, is it possible reason? Thank you
