Hi, I've always wondered if a lack of overwrite / random-write op means that updates are much faster than convention filesystems..
The fact that both (dfs, gfs) support delete op, does it mean that fragmentation will still be a big problem ? Bcoz of snapshots, I note that delete actually doesn't blow away the data until it is garbage-collected. But after gc, we should see some big holes... Also, would the lack of overwrite / random-write ops mean that the filesystem is less suitable for apps like online word-processor or even online spreadsheet / database ? Thx.
