   @rdblue The use case for tracking per-partition stats is mainly for planning purposes - estimating the number of rows (for join planning, and join ordering) and the number of files to read based on the dataset that needs to be read.
   
   As of now, the submitted change rewrites only the required files. Are suggesting the following approach:
   - Commit the transaction by including placeholders for the partition stats files
   - Asynchronously write the partition stats files
