Steve Loughran commented on HIVE-15199:
---------------------------------------
you are right, I am wrong: serves me right for commenting without staring at
the code. you should be calling; I got confused by naming.
you should be invoking
{code}
RemoteIterator<LocatedFileStatus> listFiles(Path f, boolean recursive)
{Code}
with recursive = true.
this defaults to a standard recursive treewalk; on object stores we can do an
O(1) listing of all child files, irrespective of directory depth and width. For
anything other than a flat directory, this is a significant speedup
> INSERT INTO data on S3 is replacing the old rows with the new ones
