On 64bit I have two large tables with 49M and 250M rows respectively.

Thanks very much for your reply confirming what I understood based on MonetDB architecture. Please allow me another follow-up question
Will there be an issue on a 64 bit system? Is there an algorithm/logic that I can use to identify the maximum number rows that I can load in one table based on the size of the row?

Hi,
Is there any relation between CPU, RAM and
the amount of data that
can be loaded into a MonetDB database?
I am trying to load 13.4 million rows of data
and I am getting
"Segmentation Fault" on a Linux box running
on 32 bit CPU with 4GB
RAM.
I had similar issues on a Windows box too?
Yes there are relations between the 'addressable'
memory and the
amount of data MonetDB can handle. With a 32 bit
system your adress
space is at best 4G. So if your records are larger
than about 320 bytes
13.4 Million rows cannot fit.
