Subject [jira] [Commented] (COUCHDB-1293) Support in memory databases that can replicate
Date Sat, 29 Oct 2011 15:27:32 GMT

    [ https://issues.apache.org/jira/browse/COUCHDB-1293?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13139339#comment-13139339

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.
