Thanks for the suggestion. I looked at this option a but today and found that passing the callback will also require signature changes to the ambulkdelete and amvacuumcleanup routines. This will also require us to check after x pages have been scanned inside vacuumscan and vacuumcleanup. After x pages the callback can then update the leaders progress. I am not sure if adding additional complexity to the scan/cleanup path is justified for what this patch is attempting to do. There will also be a lag of the leader updating the progress as it must scan x amount of pages before updating. Obviously, the more Pages to the scan, the longer the lag will be. Would like to hear your thoughts on the above. Regards, Sami Imseih Amazon Web Services.
