Sorry for posting another thread about GC overhead, but none of the solutions found through the forum seems to work for me.
I'm experiencing this issue with GroupBy node, reading a table with more than 77m rows and three columns.
I'm running Knime on a Windows 7, 64-bit OS, 4gb RAM,
I've already increased the heap size with Xmx3gb in the knime.ini file, increased the number of cells retained in memory, tried all the options with memory policy
but still the node doesn't work.
Working with database nodes could help?
Any other suggestion?
Thanks in advance
