> Executing single insert statements on a transactional table effects write
> performance on a s3 file system. Each insert creates a new delta directory.
> After each insert hive calculates statistics like number of file in the table
> and total size of the table. In order to calculate these, it traverses the
> directory recursively. During the recursion for each path a separate
> listStatus call is executed. In the end the more delta directory you have the
> more time it takes to calculate the statistics.
> Therefore insertion time goes up linearly:

> The fix is to use fs.listFiles(path, /**recursive**/ true) instead the
> handcrafter recursive method/
