[druid-user] Can druid load data more than machine memory?

Hey Kurt,

On Linux, since these memory pages are disk-backed, the kernel will be able to free them when under memory pressure. So the system will not OOM if you load more data than you have memory, although you will see some performance degradation due to needing to load data from disk more often.

Hi Gian,
