Category: Core Group: MonetDB5 5.2 Status: Open Resolution: None Priority: 5 Private: No Submitted By: mharrison (matt_harrison) Assigned to: Nobody/Anonymous (nobody) Summary: Memory leaks when bulk loading Initial Comment: While attempting to load 1Mil rows into a table memory use goes 700+Megs. Loading the same tables in My/postgre/sql doesn't ever take more than 20Megs! After bulk load is done memory comes down a bit (100M or so) but still stays high. Am attaching valgrind log. ---------------------------------------------------------------------- >Comment By: mharrison (matt_harrison) Date: 2007-12-22 05:42 Message: Logged In: YES user_id=1164236 Originator: YES Memory consumed by ram/top. Memory get's mmapped during bulk load? Then there's no way I'm every going to get 100+Mil rows loaded. ---------------------------------------------------------------------- Comment By: Martin Kersten (mlkersten) Date: 2007-12-22 00:21 Message: Logged In: YES user_id=490798 Originator: NO Are you referring to the on-disk size? or the memory consumption as seen by 'top' Note that the memory consumption of the ^sql are based on the memory buffer pool set aside for processing. Not the table sizes. In MonetDB you see the table size as a large memory mapped file. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=482468&aid=1856034&group_id=56967 ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
