Isn't that a regular disk, with your OS's (or SSHD's) file cache?

- mbreese 7y agoNo, in this context, it's creating a virtual disk using only RAM as a backing store. If you do this, then you can use whatever tools you'd normally use (cat, wc, grep, etc) to explore a dataset as if they were files. It's the super quick and dirty way to go if you don't want to code up a proper solution and your data fits in RAM. (assuming the data is organized in files to begin with)
