Venks, Number of columns is limited only by disk space. I have columns which are approx 2GB on disk but I believe column size is limited to the maximum size of a file in your given file system, or maybe it is 2GB. The developers are authority on max column size. Colin --- Venks <venkatesh.mantha@gmail.com> wrote:
Colin,
Do you know the size of each row? I have a table with 50 columns and could grow to 100 columns for our testing. Does this matter?

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

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

Hi,
Is there any relation between CPU, RAM
and
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
Venks wrote: the amount of data that than about 320 bytes
13.4 Million rows cannot fit.
Niels
Thanks,
