   Yes, COW will make a copy(of existing data) and merge incoming records and write a new data file. So, if you have configured to retain lets say 10 commits, 10 copies of 1 data file w/ some iterative additions will part of hudi table. If you are interested in just the latest, you can set the commits to retain config to just 1. 
   hoodie.cleaner.commits.retained
   So, this will maintain just 1 version of data file in hudi.
