Re: [infinispan-dev] [hibernate-dev] Spliting Lucene segments in Infinispan Directory
For some reason this got swallowed. Thanks for resending, Emmanuel.
My comments inline.

Smaller chunks mean smaller replication units, and finer grained
locking (although the latter may not really be useful since you want
to lock the entire 'file' each time).

For Infinispan though, I suggest not really bothering with this,
unless you feel that individual files would really be very large and
possibly too large to fit in memory - in which case chunking would
make sense again.
