Jay Kreps commented on KAFKA-1646:
----------------------------------

So [~waldenchen] next steps for this patch:
1. KIP is under discussion
2. This patch still includes no testing at all, right? We definitely need to 
remedy that
3. It would be good to get perf results for Windows/NTFS + Linux/ext4

Also, are you guys using this patch in production? If so what has been the 
experience?

> This patch is for Window platform only. In Windows platform, if there are 
> more than one replicas writing to disk, the segment log files will not be 
> consistent in disk and then consumer reading performance will be dropped down 
> greatly. This fix allocates more disk spaces when rolling a new segment, and 
> then it will improve the consumer reading performance in NTFS file system.
> This patch doesn't affect file allocation of other filesystems, for it only 
> adds statements like 'if(Os.iswindow)' or adds methods used on Windows.
