Jan Lehnardt commented on COUCHDB-1293:
---------------------------------------
I agree,
> diskutil erasevolume HFS+ "ramdisk" `hdiutil attach -nomount ram://1165430`
Started erase on disk4
Unmounting disk
Erasing
Initialized /dev/rdisk4 as a 569 MB HFS Plus volume
Mounting disk
Finished erase on disk4 ramdisk
> ln -s /Volumes/ramdisk /Users/jan/Work/couchdb/tmp/lib/ram
> curl -X PUT $COUCH/ram%2fdisk
{"ok":true}
> ls /Volumes/ramdisk/
disk.couch
seems an easy enough solution that works today. Compaction would be pretty
fast, too :)

> The summary really says it all. It would be great if we could have databases
> that live only in memory, but that could also be replicated to other URLs
> (potentially a database on disk or another node in a cluster).
> I don't think views would be necessary for the sorts of things you'd be doing
> all in memory (session data, temp data, etc.).
> I talked with Kocoloski about this around a month ago and it did not sound
> like an easy feat because of the replication. I would still like to hear what
> people have to say about it.
