Somewhat unrelated: some filesystems also provide online compression (e.g. ZFS). I think that's a more appropriate layer to apply general compression.

- darkarmani 12y agoDoesn't that mean you'll always be loading uncompressed data into memory?
- dmpk2k 12y agoIf your database has specialised compression, or keeps most data in main memory compressed (I can think of at least one that does), then this approach won't work. For almost everything else though, putting compression in the filesystem layer is better.
