Pavel Yaskevich commented on CASSANDRA-47:
------------------------------------------

Tests are passing. Does it crush on you? As I wrote before - currently to check 
real size of the file (tested only on linux because OS X FS saves empty blocks 
to the disk for some reason) you need to get a block count using 'ls -alhs', 
current patch reserves an empty space for each chunk because we need to do 
seeks while we write data using SSTableWriter.

I'm currently working to avoid that (CASSANDRA-2879 is a step in that 
direction).

> We should be able to do SSTable compression which would trade CPU for I/O 
> (almost always a good trade).
