Memory-backed Filesystem for Temporary Storage of Whisper Data – Jeff Blaine
Instead of buying and installing SSDs, storing Graphite’s whisper files in a memory-backed filesystem can be a good way to go if you have the RAM to spare. Depending on your environment, you may or may not care about losing a few minutes (or hours) of metric data. I know we certainly don’t care about losing 30 minutes, so there’s no reason for our carbon-cache instances to be scrawling to persiste
