Re: file system for streaming data

[Peter Teoh <htmldeveloper@xxxxxxxxx>]

i am not aware of filesystem-specific features for streaming data, but
at the lower level, the drivers yes:

./infiniband/hw/cxgb3/iwch_cm.c:
./media/common/saa7146_vbi.c:
./media/video/cafe_ccic.c:
./media/video/gspca/ov534.c:
./scsi/NCR_Q720.c:
./usb/gadget/inode.c:

but if u google further, there are filesystem which are implemented
for streaming data eg, OMFS.

but i don't these FS perform remarkably better than traditional filesystem.

except perhaps if u are google (which i don't know is using what
filesystem for google video, but the Google Filesystem - GFS - for its
search engine, is NOT even a kernel implementation, but a userspace
filesystem) and even so, FS is not really an important factor, but
others like storage architecture and network delivery (CDN):

But amazingly, there is something called Youtubefs:

http://www.slideshare.net/mclee/beyond-the-file-system-designing-large-scale-file-storage-and-serving

for google video, it is not really the filesystem that matters, but
more on the infrastructure like network (CDN and Akamai etc):

Check out memcached used by Youtube as well:
