I have limited memory on our system 16GB of memory and our tables have more than 2 billion records. The underlying storage is extremely fast (300MB/sec read and write and rewrite), therefore I would like to depend mainly on the storage versus placing everything in memory.
Is there an option with MonetDB which will let me only allocate 25% of the database into memory and rest seek disk? no, MonetDB will take the memory it sees fit. You database is memory mapped, which means it brings only to memory what is needed.
You may have to enlarge your swap space on your system to accommodate complicated queries, i.e., with lots of intermediates.
