RE: World folder - FakeTruth - 05-06-2011
Phew.. I just did a whole overhaul on the way stuff is saved, and it's not even done yet.
I went with the same kind of approach Notch did, now multiple chunks are saved in one file, and it's compressed! It's tiny
I created a test case:
Old format:
- 325 files
- 25,3 MB
New format:
- 6 files
- 783 KB
The new format stores a maximum of 1024 chunks ( 32 by 32 ) chunks in one file. Chunks are intelligently cached in compressed form in memory and uncompressed when they are needed which keeps the RAM usage really low (expect 2~4kb per unused chunk, ~80kb per used chunk). In addition to that, it's REALLY fast!
which is pretty cool.Data is compressed with zlib which (I think) comes with it's own corruption detection stuff, so I no longer have to check that manually
PS:
Another awesome thing is that your old data is converted to the new data ON THE FLY
So you have to do nothing, and you won't even notice it!

I still want the ability to convert my minecraft single player worlds into MCServer worlds - there's just stuff I can't be bothered building again.
Even if it was a really inneficient converter that I had to leave running for 5 hours that'd be better than nothing :S
