Hi,
I have three tables each with about 20,000,000 rows having mostly the same row_keys. Now, when I use Concatenate (Optional in) I get a Heap-space error or the JVM crashes...
These are JVM options I am using (I believe they are rather genourous)
-Dknime.expert.mode=true
-XX:PermSize=128m
-XX:MaxPermSize=1G
-Xmx16G
-Dknime.tmpdir=/pasteur/solexa2/solexa_travail/PF2/tmp
-Dknime.logfile.maxsize=10000000
-Dorg.knime.container.cellsinmemory=1000000
Do you have any suggestion on how to get this working? In the future I am expecting to have more like 100M rows per table...
(My solution would be to make the checking for uniq keys optional...)
Thanks,
Bernd
